CMP0140 — CMake 3.27.6 Documentation

# CMP0140

New in version 3.25.

The `return()` command checks its parameters.

The `OLD` behavior for this policy is to ignore any parameters given to the command. The `NEW` behavior is to check the validity of the parameters.

This policy was introduced in CMake version 3.25. CMake version 3.27.6 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.
