FindPackageMessage
|
||
|
|
------------------
|
||
|
|
|
||
|
|
.. code-block:: cmake
|
||
|
|
|
||
|
|
find_package_message(<name> "message for user" "find result details")
|
||
|
|
|
||
|
|
This function is intended to be used in FindXXX.cmake modules files.
|
||
|
|
It will print a message once for each unique find result. This is
|
||
|
|
useful for telling the user where a package was found. The first
|
||
|
|
argument specifies the name (XXX) of the package. The second argument
|
||
|
|
specifies the message to display. The third argument lists details
|
||
|
|
about the find result so that if they change the message will be
|
||
|
|
displayed again. The macro also obeys the QUIET argument to the
|
||
|
|
find_package command.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
.. code-block:: cmake
|
||
|
|
|
||
|
|
if(X11_FOUND)
|
||
|
|
find_package_message(X11 "Found X11: ${X11_X11_LIB}"
|
||
|
|
"[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")
|
||
|
|
else()
|
||
|
|
...
|
||
|
|
endif()
|
||
|
|

function(find_package_message pkg msg details)
|
||
|
|
# Avoid printing a message repeatedly for the same find result.
|
||
|
|
if(NOT ${pkg}_FIND_QUIETLY)
|
||
|
|
string(REPLACE "\n" "" details "${details}")
|

if(NOT "${details}" STREQUAL "${${DETAILS_VAR}}")
|
||
|
|
# The message has not yet been printed.
|
||
|
|
message(STATUS "${msg}")
|
||
|
|
|
||
|
|
# Save the find details in the cache to avoid printing the same
|
||
|
|
# message again.
|
||
|
|
set("${DETAILS_VAR}" "${details}"
|

CACHE INTERNAL "Details about finding ${pkg}")
