Include file check macros honor CMAKE_REQUIRED_LIBRARIES
.
In CMake 3.12 and above, the
check_include_file
macro in theCheckIncludeFile
module, thecheck_include_file_cxx
macro in theCheckIncludeFileCXX
module, and thecheck_include_files
macro in theCheckIncludeFiles
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
3.17.5 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.
