Do not re-expand variables in include and link information.
CMake 2.8.10 and lower re-evaluated values given to the include_directories, link_directories, and link_libraries commands to expand any leftover variable references at the end of the configuration step. This was for strict compatibility with VERY early CMake versions because all variable references are now normally evaluated during CMake language processing. CMake 2.8.11 and higher prefer to skip the extra evaluation.
OLD behavior for this policy is to re-evaluate the values for
strict compatibility. The
NEW behavior for this policy is to leave
the values untouched.
This policy was introduced in CMake version 2.8.11. CMake version
3.26.20230330-g57bb7e6 warns when the policy is not set and uses
OLD behavior. Use
cmake_policy() command to set it to
OLD behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
