| Include file check macros honor ``CMAKE_REQUIRED_LIBRARIES``. |
| |
| In CMake 3.12 and above, the |
| |
| * ``check_include_file`` macro in the :module:`CheckIncludeFile` module, the |
| * ``check_include_file_cxx`` macro in the |
| :module:`CheckIncludeFileCXX` module, and the |
| * ``check_include_files`` macro 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 macros. The ``NEW`` behavior of this policy is to |
| honor ``CMAKE_REQUIRED_LIBRARIES`` in the include file check macros. |
| |
| This policy was introduced in CMake version 3.12. CMake version |
| |release| warns when the policy is not set and uses ``OLD`` behavior. |
| Use the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` |
| explicitly. |
