CheckLinkerFlag: Set policies needed by the implementation
The module was added in CMake 3.18 by commit af96c0f4fa (CheckLinkerFlag: Add module to check validity of linker flags, 2020-05-16, v3.18.0-rc1~103^2), but it is still possible for projects to use it without setting policies to the 3.18 version level.
