CMP0139

New in version 3.24.

The if() command supports path comparisons using PATH_EQUAL operator.

The OLD behavior for this policy is to ignore the PATH_EQUAL operator. The NEW behavior is to interpret the PATH_EQUAL operator.

This policy was introduced in CMake version 3.24. CMake version 3.27.9 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.
