.. versionadded:: 3.12

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.
