Case sensitive <LANG>_COMPILER_ID generator expressions

CMake 2.8.12 introduced the <LANG>_COMPILER_ID generator expressions to allow comparison of the CMAKE_<LANG>_COMPILER_ID with a test value. The possible valid values are lowercase, but the comparison with the test value was performed case-insensitively.

The OLD behavior for this policy is to perform a case-insensitive comparison with the value in the <LANG>_COMPILER_ID expression. The NEW behavior for this policy is to perform a case-sensitive comparison with the value in the <LANG>_COMPILER_ID expression.

This policy was introduced in CMake version 3.0. CMake version 3.11.4 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.
