|
|
Libarchive is multi-format archive and compression library.
|
|
|
|
The module defines the following variables:
|
|
|
|
::
|
|
|
|
LibArchive_FOUND - true if libarchive was found
|
|
LibArchive_INCLUDE_DIRS - include search path
|
|
LibArchive_LIBRARIES - libraries to link
|
|
LibArchive_VERSION - libarchive 3-component version number
|
|
|
|
The module defines the following ``IMPORTED`` targets:
|
|
|
|
::
|
|
|
|
LibArchive::LibArchive - target for linking against libarchive
|
|
|
|
.. versionadded:: 3.6
|
|
Support for new libarchive 3.2 version string format.
|
|
|
|
.. versionadded:: 3.17
|
|
Provides an imported target.
