CMP0139 — CMake 3.24.1 Documentation

# 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 3.24.1 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.
