Include file check macros honor CMAKE_REQUIRED_LIBRARIES.
In CMake 3.12 and above, the
check_include_filemacro in theCheckIncludeFilemodule, thecheck_include_file_cxxmacro in theCheckIncludeFileCXXmodule, and thecheck_include_filesmacro in theCheckIncludeFilesmodule
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
3.15.3 warns when the policy is not set and uses OLD behavior.
Use the cmake_policy() command to set it to OLD or NEW
explicitly.
Note
The OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
