Include file check macros honor ``CMAKE_REQUIRED_LIBRARIES``.
|
|
|
|
In CMake 3.12 and above, the
|
|
|
|
* ``check_include_file()`` command in the :module:`CheckIncludeFile` module, the
|
|
* ``check_include_file_cxx()`` command in the
|
|
:module:`CheckIncludeFileCXX` module, and the
|
|
* ``check_include_files()`` command in the :module:`CheckIncludeFiles` module
|
|
|
|
now prefer to link the check executable to the libraries listed in the
|
|
``CMAKE_REQUIRED_LIBRARIES`` variable. This policy provides compatibility
|
|
with projects that have not been updated to expect this behavior.
|
|
|
|
The ``OLD`` behavior for this policy is to ignore ``CMAKE_REQUIRED_LIBRARIES``
|
|
in the include file check commands. The ``NEW`` behavior of this policy is to
|
|
honor ``CMAKE_REQUIRED_LIBRARIES`` in the include file check commands.
