External Project Definition
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. command:: ExternalProject_Add
|
|
|
|
The ``ExternalProject_Add()`` function creates a custom target to drive
|
|
download, update/patch, configure, build, install and test steps of an
|
|
external project:
|
|
|
|
.. code-block:: cmake
|
|
|
|
ExternalProject_Add(<name> [<option>...])
|
|
|
|
The individual steps within the process can be driven independently if
|
|
required (e.g. for CDash submission) and extra custom steps can be defined,
|
|
along with the ability to control the step dependencies. The directory
|
|
structure used for the management of the external project can also be
|
|
customized. The function supports a large number of options which can be used
|
|
to tailor the external project behavior.
|
|
|
|
**Directory Options:**
|
|
Most of the time, the default directory layout is sufficient. It is largely
|
|
an implementation detail that the main project usually doesn't need to
|
|
change. In some circumstances, however, control over the directory layout
|
|
can be useful or necessary. The directory options are potentially more
|
|
useful from the point of view that the main build can use the
|
|
:command:`ExternalProject_Get_Property` command to retrieve their values,
|
|
thereby allowing the main project to refer to build artifacts of the
|
|
external project.
|
|
|
|
``PREFIX <dir>``
|
|
Root directory for the external project. Unless otherwise noted below,
|
|
all other directories associated with the external project will be
|
|
created under here.
|
|
|
|
``TMP_DIR <dir>``
|
|
Directory in which to store temporary files.
|
|
|
|
``STAMP_DIR <dir>``
|
|
Directory in which to store the timestamps of each step. Log files from
|
|
individual steps are also created in here unless overriden by LOG_DIR
|
|
(see *Logging Options* below).
|
|
|
|
``LOG_DIR <dir>``
|
|
Directory in which to store the logs of each step.
|
|
|
|
``DOWNLOAD_DIR <dir>``
|
|
Directory in which to store downloaded files before unpacking them. This
|
|
directory is only used by the URL download method, all other download
|
|
methods use ``SOURCE_DIR`` directly instead.
|
|
|
|
``SOURCE_DIR <dir>``
|
|
Source directory into which downloaded contents will be unpacked, or for
|
|
non-URL download methods, the directory in which the repository should be
|
|
checked out, cloned, etc. If no download method is specified, this must
|
|
point to an existing directory where the external project has already
|
|
been unpacked or cloned/checked out.
|
|
|
|
.. note::
|
|
If a download method is specified, any existing contents of the source
|
|
directory may be deleted. Only the URL download method checks whether
|
|
this directory is either missing or empty before initiating the
|
|
download, stopping with an error if it is not empty. All other
|
|
download methods silently discard any previous contents of the source
|
|
directory.
|
|
|
|
``BINARY_DIR <dir>``
|
|
Specify the build directory location. This option is ignored if
|
|
``BUILD_IN_SOURCE`` is enabled.
|
|
|
|
``INSTALL_DIR <dir>``
|
|
Installation prefix to be placed in the ``<INSTALL_DIR>`` placeholder.
|
|
This does not actually configure the external project to install to
|
|
the given prefix. That must be done by passing appropriate arguments
|
|
to the external project configuration step, e.g. using ``<INSTALL_DIR>``.
|
|
|
|
If any of the above ``..._DIR`` options are not specified, their defaults
|
|
are computed as follows. If the ``PREFIX`` option is given or the
|
|
``EP_PREFIX`` directory property is set, then an external project is built
|
|
and installed under the specified prefix::
|
|
|
|
TMP_DIR = <prefix>/tmp
|
|
STAMP_DIR = <prefix>/src/<name>-stamp
|
|
DOWNLOAD_DIR = <prefix>/src
|
|
SOURCE_DIR = <prefix>/src/<name>
|
|
BINARY_DIR = <prefix>/src/<name>-build
|
|
INSTALL_DIR = <prefix>
|
|
LOG_DIR = <STAMP_DIR>
|
|
|
|
Otherwise, if the ``EP_BASE`` directory property is set then components
|
|
of an external project are stored under the specified base::
|
|
|
|
TMP_DIR = <base>/tmp/<name>
|
|
STAMP_DIR = <base>/Stamp/<name>
|
|
DOWNLOAD_DIR = <base>/Download/<name>
|
|
SOURCE_DIR = <base>/Source/<name>
|
|
BINARY_DIR = <base>/Build/<name>
|
|
INSTALL_DIR = <base>/Install/<name>
|
|
LOG_DIR = <STAMP_DIR>
|
|
|
|
If no ``PREFIX``, ``EP_PREFIX``, or ``EP_BASE`` is specified, then the
|
|
default is to set ``PREFIX`` to ``<name>-prefix``. Relative paths are
|
|
interpreted with respect to :variable:`CMAKE_CURRENT_BINARY_DIR` at the
|
|
point where ``ExternalProject_Add()`` is called.
|
|
|
|
**Download Step Options:**
|
|
A download method can be omitted if the ``SOURCE_DIR`` option is used to
|
|
point to an existing non-empty directory. Otherwise, one of the download
|
|
methods below must be specified (multiple download methods should not be
|
|
given) or a custom ``DOWNLOAD_COMMAND`` provided.
|
|
|
|
``DOWNLOAD_COMMAND <cmd>...``
|
|
Overrides the command used for the download step
|
|
(:manual:`generator expressions <cmake-generator-expressions(7)>` are
|
|
supported). If this option is specified, all other download options will
|
|
be ignored. Providing an empty string for ``<cmd>`` effectively disables
|
|
the download step.
|
|
|
|
*URL Download*
|
|
``URL <url1> [<url2>...]``
|
|
List of paths and/or URL(s) of the external project's source. When more
|
|
than one URL is given, they are tried in turn until one succeeds. A URL
|
|
may be an ordinary path in the local file system (in which case it
|
|
must be the only URL provided) or any downloadable URL supported by the
|
|
:command:`file(DOWNLOAD)` command. A local filesystem path may refer to
|
|
either an existing directory or to an archive file, whereas a URL is
|
|
expected to point to a file which can be treated as an archive. When an
|
|
archive is used, it will be unpacked automatically unless the
|
|
``DOWNLOAD_NO_EXTRACT`` option is set to prevent it. The archive type
|
|
is determined by inspecting the actual content rather than using logic
|
|
based on the file extension.
|
|
|
|
``URL_HASH <algo>=<hashValue>``
|
|
Hash of the archive file to be downloaded. The argument should be of
|
|
the form ``<algo>=<hashValue>`` where ``algo`` can be any of the hashing
|
|
algorithms supported by the :command:`file()` command. Specifying this
|
|
option is strongly recommended for URL downloads, as it ensures the
|
|
integrity of the downloaded content. It is also used as a check for a
|
|
previously downloaded file, allowing connection to the remote location
|
|
to be avoided altogether if the local directory already has a file from
|
|
an earlier download that matches the specified hash.
|
|
|
|
``URL_MD5 <md5>``
|
|
Equivalent to ``URL_HASH MD5=<md5>``.
|
|
|
|
``DOWNLOAD_NAME <fname>``
|
|
File name to use for the downloaded file. If not given, the end of the
|
|
URL is used to determine the file name. This option is rarely needed,
|
|
the default name is generally suitable and is not normally used outside
|
|
of code internal to the ``ExternalProject`` module.
|
|
|
|
``DOWNLOAD_NO_EXTRACT <bool>``
|
|
Allows the extraction part of the download step to be disabled by
|
|
passing a boolean true value for this option. If this option is not
|
|
given, the downloaded contents will be unpacked automatically if
|
|
required. If extraction has been disabled, the full path to the
|
|
downloaded file is available as ``<DOWNLOADED_FILE>`` in subsequent
|
|
steps or as the property ``DOWNLOADED_FILE`` with the
|
|
:command:`ExternalProject_Get_Property` command.
|
|
|
|
``DOWNLOAD_NO_PROGRESS <bool>``
|
|
Can be used to disable logging the download progress. If this option is
|
|
not given, download progress messages will be logged.
|
|
|
|
``TIMEOUT <seconds>``
|
|
Maximum time allowed for file download operations.
|
|
|
|
``HTTP_USERNAME <username>``
|
|
Username for the download operation if authentication is required.
|
|
|
|
``HTTP_PASSWORD <password>``
|
|
Password for the download operation if authentication is required.
|
|
|
|
``HTTP_HEADER <header1> [<header2>...]``
|
|
Provides an arbitrary list of HTTP headers for the download operation.
|
|
This can be useful for accessing content in systems like AWS, etc.
|
|
|
|
``TLS_VERIFY <bool>``
|
|
Specifies whether certificate verification should be performed for
|
|
https URLs. If this option is not provided, the default behavior is
|
|
determined by the ``CMAKE_TLS_VERIFY`` variable (see
|
|
:command:`file(DOWNLOAD)`). If that is also not set, certificate
|
|
verification will not be performed. In situations where ``URL_HASH``
|
|
cannot be provided, this option can be an alternative verification
|
|
measure.
|
|
|
|
``TLS_CAINFO <file>``
|
|
Specify a custom certificate authority file to use if ``TLS_VERIFY``
|
|
is enabled. If this option is not specified, the value of the
|
|
``CMAKE_TLS_CAINFO`` variable will be used instead (see
|
|
:command:`file(DOWNLOAD)`)
|
|
|
|
``NETRC <level>``
|
|
Specify whether the .netrc file is to be used for operation. If this
|
|
option is not specified, the value of the ``CMAKE_NETRC`` variable
|
|
will be used instead (see :command:`file(DOWNLOAD)`)
|
|
Valid levels are:
|
|
|
|
``IGNORED``
|
|
The .netrc file is ignored.
|
|
This is the default.
|
|
``OPTIONAL``
|
|
The .netrc file is optional, and information in the URL is preferred.
|
|
The file will be scanned to find which ever information is not specified
|
|
in the URL.
|
|
``REQUIRED``
|
|
The .netrc file is required, and information in the URL is ignored.
|
|
|
|
``NETRC_FILE <file>``
|
|
Specify an alternative .netrc file to the one in your home directory
|
|
if the ``NETRC`` level is ``OPTIONAL`` or ``REQUIRED``. If this option
|
|
is not specified, the value of the ``CMAKE_NETRC_FILE`` variable will
|
|
be used instead (see :command:`file(DOWNLOAD)`)
|
|
|
|
*Git*
|
|
NOTE: A git version of 1.6.5 or later is required if this download method
|
|
is used.
|
|
|
|
``GIT_REPOSITORY <url>``
|
|
URL of the git repository. Any URL understood by the ``git`` command
|
|
may be used.
|
|
|
|
``GIT_TAG <tag>``
|
|
Git branch name, tag or commit hash. Note that branch names and tags
|
|
should generally be specified as remote names (i.e. ``origin/myBranch``
|
|
rather than simply ``myBranch``). This ensures that if the remote end
|
|
has its tag moved or branch rebased or history rewritten, the local
|
|
clone will still be updated correctly. In general, however, specifying
|
|
a commit hash should be preferred for a number of reasons:
|
|
|
|
- If the local clone already has the commit corresponding to the hash,
|
|
no ``git fetch`` needs to be performed to check for changes each time
|
|
CMake is re-run. This can result in a significant speed up if many
|
|
external projects are being used.
|
|
- Using a specific git hash ensures that the main project's own history
|
|
is fully traceable to a specific point in the external project's
|
|
evolution. If a branch or tag name is used instead, then checking out
|
|
a specific commit of the main project doesn't necessarily pin the
|
|
whole build to a specific point in the life of the external project.
|
|
The lack of such deterministic behavior makes the main project lose
|
|
traceability and repeatability.
|
|
|
|
``GIT_REMOTE_NAME <name>``
|
|
The optional name of the remote. If this option is not specified, it
|
|
defaults to ``origin``.
|
|
|
|
``GIT_SUBMODULES <module>...``
|
|
Specific git submodules that should also be updated. If this option is
|
|
not provided, all git submodules will be updated.
|
|
|
|
``GIT_SHALLOW <bool>``
|
|
When this option is enabled, the ``git clone`` operation will be given
|
|
the ``--depth 1`` option. This performs a shallow clone, which avoids
|
|
downloading the whole history and instead retrieves just the commit
|
|
denoted by the ``GIT_TAG`` option.
|
|
|
|
``GIT_PROGRESS <bool>``
|
|
When enabled, this option instructs the ``git clone`` operation to
|
|
report its progress by passing it the ``--progress`` option. Without
|
|
this option, the clone step for large projects may appear to make the
|
|
build stall, since nothing will be logged until the clone operation
|
|
finishes. While this option can be used to provide progress to prevent
|
|
the appearance of the build having stalled, it may also make the build
|
|
overly noisy if lots of external projects are used.
|
|
|
|
``GIT_CONFIG <option1> [<option2>...]``
|
|
Specify a list of config options to pass to ``git clone``. Each option
|
|
listed will be transformed into its own ``--config <option>`` on the
|
|
``git clone`` command line, with each option required to be in the
|
|
form ``key=value``.
|
|
|
|
*Subversion*
|
|
``SVN_REPOSITORY <url>``
|
|
URL of the Subversion repository.
|
|
|
|
``SVN_REVISION -r<rev>``
|
|
Revision to checkout from the Subversion repository.
|
|
|
|
``SVN_USERNAME <username>``
|
|
Username for the Subversion checkout and update.
|
|
|
|
``SVN_PASSWORD <password>``
|
|
Password for the Subversion checkout and update.
|
|
|
|
``SVN_TRUST_CERT <bool>``
|
|
Specifies whether to trust the Subversion server site certificate. If
|
|
enabled, the ``--trust-server-cert`` option is passed to the ``svn``
|
|
checkout and update commands.
|
|
|
|
*Mercurial*
|
|
``HG_REPOSITORY <url>``
|
|
URL of the mercurial repository.
|
|
|
|
``HG_TAG <tag>``
|
|
Mercurial branch name, tag or commit id.
|
|
|
|
*CVS*
|
|
``CVS_REPOSITORY <cvsroot>``
|
|
CVSROOT of the CVS repository.
|
|
|
|
``CVS_MODULE <mod>``
|
|
Module to checkout from the CVS repository.
|
|
|
|
``CVS_TAG <tag>``
|
|
Tag to checkout from the CVS repository.
|
|
|
|
**Update/Patch Step Options:**
|
|
Whenever CMake is re-run, by default the external project's sources will be
|
|
updated if the download method supports updates (e.g. a git repository
|
|
would be checked if the ``GIT_TAG`` does not refer to a specific commit).
|
|
|
|
``UPDATE_COMMAND <cmd>...``
|
|
Overrides the download method's update step with a custom command.
|
|
The command may use
|
|
:manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
|
|
``UPDATE_DISCONNECTED <bool>``
|
|
When enabled, this option causes the update step to be skipped. It does
|
|
not, however, prevent the download step. The update step can still be
|
|
added as a step target (see :command:`ExternalProject_Add_StepTargets`)
|
|
and called manually. This is useful if you want to allow developers to
|
|
build the project when disconnected from the network (the network may
|
|
still be needed for the download step though).
|
|
|
|
When this option is present, it is generally advisable to make the value
|
|
a cache variable under the developer's control rather than hard-coding
|
|
it. If this option is not present, the default value is taken from the
|
|
``EP_UPDATE_DISCONNECTED`` directory property. If that is also not
|
|
defined, updates are performed as normal. The ``EP_UPDATE_DISCONNECTED``
|
|
directory property is intended as a convenience for controlling the
|
|
``UPDATE_DISCONNECTED`` behavior for an entire section of a project's
|
|
directory hierarchy and may be a more convenient method of giving
|
|
developers control over whether or not to perform updates (assuming the
|
|
project also provides a cache variable or some other convenient method
|
|
for setting the directory property).
|
|
|
|
``PATCH_COMMAND <cmd>...``
|
|
Specifies a custom command to patch the sources after an update. By
|
|
default, no patch command is defined. Note that it can be quite difficult
|
|
to define an appropriate patch command that performs robustly, especially
|
|
for download methods such as git where changing the ``GIT_TAG`` will not
|
|
discard changes from a previous patch, but the patch command will be
|
|
called again after updating to the new tag.
|
|
|
|
**Configure Step Options:**
|
|
The configure step is run after the download and update steps. By default,
|
|
the external project is assumed to be a CMake project, but this can be
|
|
overridden if required.
|
|
|
|
``CONFIGURE_COMMAND <cmd>...``
|
|
The default configure command runs CMake with options based on the main
|
|
project. For non-CMake external projects, the ``CONFIGURE_COMMAND``
|
|
option must be used to override this behavior
|
|
(:manual:`generator expressions <cmake-generator-expressions(7)>` are
|
|
supported). For projects that require no configure step, specify this
|
|
option with an empty string as the command to execute.
|
|
|
|
``CMAKE_COMMAND /.../cmake``
|
|
Specify an alternative cmake executable for the configure step (use an
|
|
absolute path). This is generally not recommended, since it is
|
|
usually desirable to use the same CMake version throughout the whole
|
|
build. This option is ignored if a custom configure command has been
|
|
specified with ``CONFIGURE_COMMAND``.
|
|
|
|
``CMAKE_GENERATOR <gen>``
|
|
Override the CMake generator used for the configure step. Without this
|
|
option, the same generator as the main build will be used. This option is
|
|
ignored if a custom configure command has been specified with the
|
|
``CONFIGURE_COMMAND`` option.
|
|
|
|
``CMAKE_GENERATOR_PLATFORM <platform>``
|
|
Pass a generator-specific platform name to the CMake command (see
|
|
:variable:`CMAKE_GENERATOR_PLATFORM`). It is an error to provide this
|
|
option without the ``CMAKE_GENERATOR`` option.
|
|
|
|
``CMAKE_GENERATOR_TOOLSET <toolset>``
|
|
Pass a generator-specific toolset name to the CMake command (see
|
|
:variable:`CMAKE_GENERATOR_TOOLSET`). It is an error to provide this
|
|
option without the ``CMAKE_GENERATOR`` option.
|
|
|
|
``CMAKE_GENERATOR_INSTANCE <instance>``
|
|
Pass a generator-specific instance selection to the CMake command (see
|
|
:variable:`CMAKE_GENERATOR_INSTANCE`). It is an error to provide this
|
|
option without the ``CMAKE_GENERATOR`` option.
|
|
|
|
``CMAKE_ARGS <arg>...``
|
|
The specified arguments are passed to the ``cmake`` command line. They
|
|
can be any argument the ``cmake`` command understands, not just cache
|
|
values defined by ``-D...`` arguments (see also
|
|
:manual:`CMake Options <cmake(1)>`). In addition, arguments may use
|
|
:manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
|
|
``CMAKE_CACHE_ARGS <arg>...``
|
|
This is an alternate way of specifying cache variables where command line
|
|
length issues may become a problem. The arguments are expected to be in
|
|
the form ``-Dvar:STRING=value``, which are then transformed into
|
|
CMake :command:`set` commands with the ``FORCE`` option used. These
|
|
``set()`` commands are written to a pre-load script which is then applied
|
|
using the :manual:`cmake -C <cmake(1)>` command line option. Arguments
|
|
may use :manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
|
|
``CMAKE_CACHE_DEFAULT_ARGS <arg>...``
|
|
This is the same as the ``CMAKE_CACHE_ARGS`` option except the ``set()``
|
|
commands do not include the ``FORCE`` keyword. This means the values act
|
|
as initial defaults only and will not override any variables already set
|
|
from a previous run. Use this option with care, as it can lead to
|
|
different behavior depending on whether the build starts from a fresh
|
|
build directory or re-uses previous build contents.
|
|
|
|
``SOURCE_SUBDIR <dir>``
|
|
When no ``CONFIGURE_COMMAND`` option is specified, the configure step
|
|
assumes the external project has a ``CMakeLists.txt`` file at the top of
|
|
its source tree (i.e. in ``SOURCE_DIR``). The ``SOURCE_SUBDIR`` option
|
|
can be used to point to an alternative directory within the source tree
|
|
to use as the top of the CMake source tree instead. This must be a
|
|
relative path and it will be interpreted as being relative to
|
|
``SOURCE_DIR``. When ``BUILD_IN_SOURCE 1`` is specified, the
|
|
``BUILD_COMMAND`` is used to point to an alternative directory within the
|
|
source tree.
|
|
|
|
**Build Step Options:**
|
|
If the configure step assumed the external project uses CMake as its build
|
|
system, the build step will also. Otherwise, the build step will assume a
|
|
Makefile-based build and simply run ``make`` with no arguments as the
|
|
default build step. This can be overridden with custom build commands if
|
|
required.
|
|
|
|
``BUILD_COMMAND <cmd>...``
|
|
Overrides the default build command
|
|
(:manual:`generator expressions <cmake-generator-expressions(7)>` are
|
|
supported). If this option is not given, the default build command will
|
|
be chosen to integrate with the main build in the most appropriate way
|
|
(e.g. using recursive ``make`` for Makefile generators or
|
|
``cmake --build`` if the project uses a CMake build). This option can be
|
|
specified with an empty string as the command to make the build step do
|
|
nothing.
|
|
|
|
``BUILD_IN_SOURCE <bool>``
|
|
When this option is enabled, the build will be done directly within the
|
|
external project's source tree. This should generally be avoided, the use
|
|
of a separate build directory is usually preferred, but it can be useful
|
|
when the external project assumes an in-source build. The ``BINARY_DIR``
|
|
option should not be specified if building in-source.
|
|
|
|
``BUILD_ALWAYS <bool>``
|
|
Enabling this option forces the build step to always be run. This can be
|
|
the easiest way to robustly ensure that the external project's own build
|
|
dependencies are evaluated rather than relying on the default
|
|
success timestamp-based method. This option is not normally needed unless
|
|
developers are expected to modify something the external project's build
|
|
depends on in a way that is not detectable via the step target
|
|
dependencies (e.g. ``SOURCE_DIR`` is used without a download method and
|
|
developers might modify the sources in ``SOURCE_DIR``).
|
|
|
|
``BUILD_BYPRODUCTS <file>...``
|
|
Specifies files that will be generated by the build command but which
|
|
might or might not have their modification time updated by subsequent
|
|
builds. These ultimately get passed through as ``BYPRODUCTS`` to the
|
|
build step's own underlying call to :command:`add_custom_command`.
|
|
|
|
**Install Step Options:**
|
|
If the configure step assumed the external project uses CMake as its build
|
|
system, the install step will also. Otherwise, the install step will assume
|
|
a Makefile-based build and simply run ``make install`` as the default build
|
|
step. This can be overridden with custom install commands if required.
|
|
|
|
``INSTALL_COMMAND <cmd>...``
|
|
The external project's own install step is invoked as part of the main
|
|
project's *build*. It is done after the external project's build step
|
|
and may be before or after the external project's test step (see the
|
|
``TEST_BEFORE_INSTALL`` option below). The external project's install
|
|
rules are not part of the main project's install rules, so if anything
|
|
from the external project should be installed as part of the main build,
|
|
these need to be specified in the main build as additional
|
|
:command:`install` commands. The default install step builds the
|
|
``install`` target of the external project, but this can be overridden
|
|
with a custom command using this option
|
|
(:manual:`generator expressions <cmake-generator-expressions(7)>` are
|
|
supported). Passing an empty string as the ``<cmd>`` makes the install
|
|
step do nothing.
|
|
|
|
**Test Step Options:**
|
|
The test step is only defined if at least one of the following ``TEST_...``
|
|
options are provided.
|
|
|
|
``TEST_COMMAND <cmd>...``
|
|
Overrides the default test command
|
|
(:manual:`generator expressions <cmake-generator-expressions(7)>` are
|
|
supported). If this option is not given, the default behavior of the test
|
|
step is to build the external project's own ``test`` target. This option
|
|
can be specified with ``<cmd>`` as an empty string, which allows the test
|
|
step to still be defined, but it will do nothing. Do not specify any of
|
|
the other ``TEST_...`` options if providing an empty string as the test
|
|
command, but prefer to omit all ``TEST_...`` options altogether if the
|
|
test step target is not needed.
|
|
|
|
``TEST_BEFORE_INSTALL <bool>``
|
|
When this option is enabled, the test step will be executed before the
|
|
install step. The default behavior is for the test step to run after the
|
|
install step.
|
|
|
|
``TEST_AFTER_INSTALL <bool>``
|
|
This option is mainly useful as a way to indicate that the test step is
|
|
desired but all default behavior is sufficient. Specifying this option
|
|
with a boolean true value ensures the test step is defined and that it
|
|
comes after the install step. If both ``TEST_BEFORE_INSTALL`` and
|
|
``TEST_AFTER_INSTALL`` are enabled, the latter is silently ignored.
|
|
|
|
``TEST_EXCLUDE_FROM_MAIN <bool>``
|
|
If enabled, the main build's default ALL target will not depend on the
|
|
test step. This can be a useful way of ensuring the test step is defined
|
|
but only gets invoked when manually requested.
|
|
|
|
**Output Logging Options:**
|
|
Each of the following ``LOG_...`` options can be used to wrap the relevant
|
|
step in a script to capture its output to files. The log files will be
|
|
created in ``LOG_DIR`` if supplied or otherwise the ``STAMP_DIR``
|
|
directory with step-specific file names.
|
|
|
|
``LOG_DOWNLOAD <bool>``
|
|
When enabled, the output of the download step is logged to files.
|
|
|
|
``LOG_UPDATE <bool>``
|
|
When enabled, the output of the update step is logged to files.
|
|
|
|
``LOG_PATCH <bool>``
|
|
When enabled, the output of the patch step is logged to files.
|
|
|
|
``LOG_CONFIGURE <bool>``
|
|
When enabled, the output of the configure step is logged to files.
|
|
|
|
``LOG_BUILD <bool>``
|
|
When enabled, the output of the build step is logged to files.
|
|
|
|
``LOG_INSTALL <bool>``
|
|
When enabled, the output of the install step is logged to files.
|
|
|
|
``LOG_TEST <bool>``
|
|
When enabled, the output of the test step is logged to files.
|
|
|
|
``LOG_MERGED_STDOUTERR <bool>``
|
|
When enabled, stdout and stderr will be merged for any step whose
|
|
output is being logged to files.
|
|
|
|
``LOG_OUTPUT_ON_FAILURE <bool>``
|
|
This option only has an effect if at least one of the other ``LOG_<step>``
|
|
options is enabled. If an error occurs for a step which has logging to
|
|
file enabled, that step's output will be printed to the console if
|
|
``LOG_OUTPUT_ON_FAILURE`` is set to true. For cases where a large amount
|
|
of output is recorded, just the end of that output may be printed to the
|
|
console.
|
|
|
|
**Terminal Access Options:**
|
|
Steps can be given direct access to the terminal in some cases. Giving a
|
|
step access to the terminal may allow it to receive terminal input if
|
|
required, such as for authentication details not provided by other options.
|
|
With the :generator:`Ninja` generator, these options place the steps in the
|
|
``console`` :prop_gbl:`job pool <JOB_POOLS>`. Each step can be given access
|
|
to the terminal individually via the following options:
|
|
|
|
``USES_TERMINAL_DOWNLOAD <bool>``
|
|
Give the download step access to the terminal.
|
|
|
|
``USES_TERMINAL_UPDATE <bool>``
|
|
Give the update step access to the terminal.
|
|
|
|
``USES_TERMINAL_CONFIGURE <bool>``
|
|
Give the configure step access to the terminal.
|
|
|
|
``USES_TERMINAL_BUILD <bool>``
|
|
Give the build step access to the terminal.
|
|
|
|
``USES_TERMINAL_INSTALL <bool>``
|
|
Give the install step access to the terminal.
|
|
|
|
``USES_TERMINAL_TEST <bool>``
|
|
Give the test step access to the terminal.
|
|
|
|
**Target Options:**
|
|
``DEPENDS <targets>...``
|
|
Specify other targets on which the external project depends. The other
|
|
targets will be brought up to date before any of the external project's
|
|
steps are executed. Because the external project uses additional custom
|
|
targets internally for each step, the ``DEPENDS`` option is the most
|
|
convenient way to ensure all of those steps depend on the other targets.
|
|
Simply doing
|
|
:command:`add_dependencies(\<name\> \<targets\>) <add_dependencies>` will
|
|
not make any of the steps dependent on ``<targets>``.
|
|
|
|
``EXCLUDE_FROM_ALL <bool>``
|
|
When enabled, this option excludes the external project from the default
|
|
ALL target of the main build.
|
|
|
|
``STEP_TARGETS <step-target>...``
|
|
Generate custom targets for the specified steps. This is required if the
|
|
steps need to be triggered manually or if they need to be used as
|
|
dependencies of other targets. If this option is not specified, the
|
|
default value is taken from the ``EP_STEP_TARGETS`` directory property.
|
|
See :command:`ExternalProject_Add_Step` below for further discussion of
|
|
the effects of this option.
|
|
|
|
``INDEPENDENT_STEP_TARGETS <step-target>...``
|
|
Generate custom targets for the specified steps and prevent these targets
|
|
from having the usual dependencies applied to them. If this option is not
|
|
specified, the default value is taken from the
|
|
``EP_INDEPENDENT_STEP_TARGETS`` directory property. This option is mostly
|
|
useful for allowing individual steps to be driven independently, such as
|
|
for a CDash setup where each step should be initiated and reported
|
|
individually rather than as one whole build. See
|
|
:command:`ExternalProject_Add_Step` below for further discussion of the
|
|
effects of this option.
|
|
|
|
**Miscellaneous Options:**
|
|
``LIST_SEPARATOR <sep>``
|
|
For any of the various ``..._COMMAND`` options, replace ``;`` with
|
|
``<sep>`` in the specified command lines. This can be useful where list
|
|
variables may be given in commands where they should end up as
|
|
space-separated arguments (``<sep>`` would be a single space character
|
|
string in this case).
|
|
|
|
``COMMAND <cmd>...``
|
|
Any of the other ``..._COMMAND`` options can have additional commands
|
|
appended to them by following them with as many ``COMMAND ...`` options
|
|
as needed
|
|
(:manual:`generator expressions <cmake-generator-expressions(7)>` are
|
|
supported). For example:
|
|
|
|
.. code-block:: cmake
|
|
|
|
ExternalProject_Add(example
|
|
... # Download options, etc.
|
|
BUILD_COMMAND ${CMAKE_COMMAND} -E echo "Starting $<CONFIG> build"
|
|
COMMAND ${CMAKE_COMMAND} --build <BINARY_DIR> --config $<CONFIG>
|
|
COMMAND ${CMAKE_COMMAND} -E echo "$<CONFIG> build complete"
|
|
)
|
|
|
|
It should also be noted that each build step is created via a call to
|
|
:command:`ExternalProject_Add_Step`. See that command's documentation for the
|
|
automatic substitutions that are supported for some options.
|
|
|
|
Obtaining Project Properties
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
.. command:: ExternalProject_Get_Property
|
|
|
|
The ``ExternalProject_Get_Property()`` function retrieves external project
|
|
target properties:
|
|
|
|
.. code-block:: cmake
|
|
|
|
ExternalProject_Get_Property(<name> <prop1> [<prop2>...])
|
|
|
|
The function stores property values in variables of the same name. Property
|
|
names correspond to the keyword argument names of ``ExternalProject_Add()``.
|
|
For example, the source directory might be retrieved like so:
|
|
|
|
.. code-block:: cmake
|
|
|
|
ExternalProject_Get_property(myExtProj SOURCE_DIR)
|
|
message("Source dir of myExtProj = ${SOURCE_DIR}")
|
|
|
|
Explicit Step Management
|
|
^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The ``ExternalProject_Add()`` function on its own is often sufficient for
|
|
incorporating an external project into the main build. Certain scenarios
|
|
require additional work to implement desired behavior, such as adding in a
|
|
custom step or making steps available as manually triggerable targets. The
|
|
``ExternalProject_Add_Step()``, ``ExternalProject_Add_StepTargets()`` and
|
|
``ExternalProject_Add_StepDependencies`` functions provide the lower level
|
|
control needed to implement such step-level capabilities.
|
|
|
|
.. command:: ExternalProject_Add_Step
|
|
|
|
The ``ExternalProject_Add_Step()`` function specifies an additional custom
|
|
step for an external project defined by an earlier call to
|
|
:command:`ExternalProject_Add`:
|
|
|
|
.. code-block:: cmake
|
|
|
|
ExternalProject_Add_Step(<name> <step> [<option>...])
|
|
|
|
``<name>`` is the same as the name passed to the original call to
|
|
:command:`ExternalProject_Add`. The specified ``<step>`` must not be one of
|
|
the pre-defined steps (``mkdir``, ``download``, ``update``, ``skip-update``,
|
|
``patch``, ``configure``, ``build``, ``install`` or ``test``). The supported
|
|
options are:
|
|
|
|
``COMMAND <cmd>...``
|
|
The command line to be executed by this custom step
|
|
(:manual:`generator expressions <cmake-generator-expressions(7)>` are
|
|
supported). This option can be repeated multiple times to specify multiple
|
|
commands to be executed in order.
|
|
|
|
``COMMENT "<text>..."``
|
|
Text to be printed when the custom step executes.
|
|
|
|
``DEPENDEES <step>...``
|
|
Other steps (custom or pre-defined) on which this step depends.
|
|
|
|
``DEPENDERS <step>...``
|
|
Other steps (custom or pre-defined) that depend on this new custom step.
|
|
|
|
``DEPENDS <file>...``
|
|
Files on which this custom step depends.
|
|
|
|
``BYPRODUCTS <file>...``
|
|
Files that will be generated by this custom step but which might or might
|
|
not have their modification time updated by subsequent builds. This list of
|
|
files will ultimately be passed through as the ``BYPRODUCTS`` option to the
|
|
:command:`add_custom_command` used to implement the custom step internally.
|
|
|
|
``ALWAYS <bool>``
|
|
When enabled, this option specifies that the custom step should always be
|
|
run (i.e. that it is always considered out of date).
|
|
|
|
``EXCLUDE_FROM_MAIN <bool>``
|
|
When enabled, this option specifies that the external project's main target
|
|
does not depend on the custom step.
|
|
|
|
``WORKING_DIRECTORY <dir>``
|
|
Specifies the working directory to set before running the custom step's
|
|
command. If this option is not specified, the directory will be the value
|
|
of the :variable:`CMAKE_CURRENT_BINARY_DIR` at the point where
|
|
``ExternalProject_Add_Step()`` was called.
|
|
|
|
``LOG <bool>``
|
|
If set, this causes the output from the custom step to be captured to files
|
|
in the external project's ``LOG_DIR`` if supplied or ``STAMP_DIR``.
|
|
|
|
``USES_TERMINAL <bool>``
|
|
If enabled, this gives the custom step direct access to the terminal if
|
|
possible.
|
|
|
|
The command line, comment, working directory and byproducts of every
|
|
standard and custom step are processed to replace the tokens
|
|
``<SOURCE_DIR>``, ``<SOURCE_SUBDIR>``, ``<BINARY_DIR>``, ``<INSTALL_DIR>``
|
|
``<TMP_DIR>``, ``<DOWNLOAD_DIR>`` and ``<DOWNLOADED_FILE>`` with their
|
|
corresponding property values defined in the original call to
|
|
:command:`ExternalProject_Add`.
|
|
|
|
.. command:: ExternalProject_Add_StepTargets
|
|
|
|
The ``ExternalProject_Add_StepTargets()`` function generates targets for the
|
|
steps listed. The name of each created target will be of the form
|
|
``<name>-<step>``:
|
|
|
|
.. code-block:: cmake
|
|
|
|
ExternalProject_Add_StepTargets(<name> [NO_DEPENDS] <step1> [<step2>...])
|
|
|
|
Creating a target for a step allows it to be used as a dependency of another
|
|
target or to be triggered manually. Having targets for specific steps also
|
|
allows them to be driven independently of each other by specifying targets on
|
|
build command lines. For example, you may be submitting to a sub-project
|
|
based dashboard where you want to drive the configure portion of the build,
|
|
then submit to the dashboard, followed by the build portion, followed
|
|
by tests. If you invoke a custom target that depends on a step halfway
|
|
through the step dependency chain, then all the previous steps will also run
|
|
to ensure everything is up to date.
|
|
|
|
If the ``NO_DEPENDS`` option is specified, the step target will not depend on
|
|
the dependencies of the external project (i.e. on any dependencies of the
|
|
``<name>`` custom target created by :command:`ExternalProject_Add`). This is
|
|
usually safe for the ``download``, ``update`` and ``patch`` steps, since they
|
|
do not typically require that the dependencies are updated and built. Using
|
|
``NO_DEPENDS`` for any of the other pre-defined steps, however, may break
|
|
parallel builds. Only use ``NO_DEPENDS`` where it is certain that the named
|
|
steps genuinely do not have dependencies. For custom steps, consider whether
|
|
or not the custom commands require the dependencies to be configured, built
|
|
and installed.
|
|
|
|
Internally, :command:`ExternalProject_Add` calls
|
|
:command:`ExternalProject_Add_Step` to create each step. If any
|
|
``STEP_TARGETS`` or ``INDEPENDENT_STEP_TARGETS`` were specified, then
|
|
``ExternalProject_Add_StepTargets()`` will also be called after
|
|
:command:`ExternalProject_Add_Step`. ``INDEPENDENT_STEP_TARGETS`` have the
|
|
``NO_DEPENDS`` option set, whereas ``STEP_TARGETS`` do not. Other than that,
|
|
the two options result in ``ExternalProject_Add_StepTargets()`` being called
|
|
in the same way. Even if a step is not mentioned in either of those two
|
|
options, ``ExternalProject_Add_StepTargets()`` can still be called later to
|
|
manually define a target for the step.
|
|
|
|
The ``STEP_TARGETS`` and ``INDEPENDENT_STEP_TARGETS`` options for
|
|
:command:`ExternalProject_Add` are generally the easiest way to ensure
|
|
targets are created for specific steps of interest. For custom steps,
|
|
``ExternalProject_Add_StepTargets()`` must be called explicitly if a target
|
|
should also be created for that custom step. An alternative to these two
|
|
options is to populate the ``EP_STEP_TARGETS`` and
|
|
``EP_INDEPENDENT_STEP_TARGETS`` directory properties. These act as defaults
|
|
for the step target options and can save having to repeatedly specify the
|
|
same set of step targets when multiple external projects are being defined.
|
|
|
|
.. command:: ExternalProject_Add_StepDependencies
|
|
|
|
The ``ExternalProject_Add_StepDependencies()`` function can be used to add
|
|
dependencies to a step. The dependencies added must be targets CMake already
|
|
knows about (these can be ordinary executable or library targets, custom
|
|
targets or even step targets of another external project):
|
|
|
|
.. code-block:: cmake
|
|
|
|
ExternalProject_Add_StepDependencies(<name> <step> <target1> [<target2>...])
|
|
|
|
This function takes care to set both target and file level dependencies and
|
|
will ensure that parallel builds will not break. It should be used instead of
|
|
:command:`add_dependencies` whenever adding a dependency for some of the step
|
|
targets generated by the ``ExternalProject`` module.
|
|
|
|
Examples
|
|
^^^^^^^^
|
|
|
|
The following example shows how to download and build a hypothetical project
|
|
called *FooBar* from github:
|
|
|
|
.. code-block:: cmake
|
|
|
|
include(ExternalProject)
|
|
ExternalProject_Add(foobar
|
|
GIT_REPOSITORY git@github.com:FooCo/FooBar.git
|
|
GIT_TAG origin/release/1.2.3
|
|
)
|
|
|
|
For the sake of the example, also define a second hypothetical external project
|
|
called *SecretSauce*, which is downloaded from a web server. Two URLs are given
|
|
to take advantage of a faster internal network if available, with a fallback to
|
|
a slower external server. The project is a typical ``Makefile`` project with no
|
|
configure step, so some of the default commands are overridden. The build is
|
|
only required to build the *sauce* target:
|
|
|
|
.. code-block:: cmake
|
|
|
|
find_program(MAKE_EXE NAMES gmake nmake make)
|
|
ExternalProject_Add(secretsauce
|
|
URL http://intranet.somecompany.com/artifacts/sauce-2.7.tgz
|
|
https://www.somecompany.com/downloads/sauce-2.7.zip
|
|
URL_HASH MD5=d41d8cd98f00b204e9800998ecf8427e
|
|
CONFIGURE_COMMAND ""
|
|
BUILD_COMMAND ${MAKE_EXE} sauce
|
|
)
|
|
|
|
Suppose the build step of ``secretsauce`` requires that ``foobar`` must already
|
|
be built. This could be enforced like so:
|
|
|
|
.. code-block:: cmake
|
|
|
|
ExternalProject_Add_StepDependencies(secretsauce build foobar)
|
|
|
|
Another alternative would be to create a custom target for ``foobar``'s build
|
|
step and make ``secretsauce`` depend on that rather than the whole ``foobar``
|
|
project. This would mean ``foobar`` only needs to be built, it doesn't need to
|
|
run its install or test steps before ``secretsauce`` can be built. The
|
|
dependency can also be defined along with the ``secretsauce`` project:
|
|
|
|
.. code-block:: cmake
|
|
|
|
ExternalProject_Add_StepTargets(foobar build)
|
|
ExternalProject_Add(secretsauce
|
|
URL http://intranet.somecompany.com/artifacts/sauce-2.7.tgz
|
|
https://www.somecompany.com/downloads/sauce-2.7.zip
|
|
URL_HASH MD5=d41d8cd98f00b204e9800998ecf8427e
|
|
CONFIGURE_COMMAND ""
|
|
BUILD_COMMAND ${MAKE_EXE} sauce
|
|
DEPENDS foobar-build
|
|
)
|
|
|
|
Instead of calling :command:`ExternalProject_Add_StepTargets`, the target could
|
|
be defined along with the ``foobar`` project itself:
|
|
|
|
.. code-block:: cmake
|
|
|
|
ExternalProject_Add(foobar
|
|
GIT_REPOSITORY git@github.com:FooCo/FooBar.git
|
|
GIT_TAG origin/release/1.2.3
|
|
STEP_TARGETS build
|
|
)
|
|
|
|
If many external projects should have the same set of step targets, setting a
|
|
directory property may be more convenient. The ``build`` step target could be
|
|
created automatically by setting the ``EP_STEP_TARGETS`` directory property
|
|
before creating the external projects with :command:`ExternalProject_Add`:
|
|
|
|
.. code-block:: cmake
|
|
|
|
set_property(DIRECTORY PROPERTY EP_STEP_TARGETS build)
|
|
|
|
Lastly, suppose that ``secretsauce`` provides a script called ``makedoc`` which
|
|
can be used to generate its own documentation. Further suppose that the script
|
|
expects the output directory to be provided as the only parameter and that it
|
|
should be run from the ``secretsauce`` source directory. A custom step and a
|
|
custom target to trigger the script can be defined like so:
|
|
|
|
.. code-block:: cmake
|
|
|
|
ExternalProject_Add_Step(secretsauce docs
|
|
COMMAND <SOURCE_DIR>/makedoc <BINARY_DIR>
|
|
WORKING_DIRECTORY <SOURCE_DIR>
|
|
COMMENT "Building secretsauce docs"
|
|
ALWAYS TRUE
|
|
EXCLUDE_FROM_MAIN TRUE
|
|
)
|
|
ExternalProject_Add_StepTargets(secretsauce docs)
|
|
|
|
The custom step could then be triggered from the main build like so::
|
|
|
|
cmake --build . --target secretsauce-docs
|
|
|
|
