target_compile_options() now honors BEFORE keyword in all scopes.

In CMake 3.16 and below the target_compile_options() ignores the BEFORE keyword in private scope. CMake 3.17 and later honors BEFORE keyword in all scopes. This policy provides compatibility for projects that have not been updated to expect the new behavior.

The OLD behavior for this policy is to not honor BEFORE keyword in private scope. The NEW behavior of this policy is to honor BEFORE keyword in all scopes.

This policy was introduced in CMake version 3.17. Use the cmake_policy() command to set it to OLD or NEW explicitly. Unlike many policies, CMake version 3.17.5 does not warn when this policy is not set and simply uses OLD behavior.

Note

The OLD behavior of a policy is deprecated by definition and may be removed in a future version of CMake.
