CMP0140 — CMake 3.29.6 Documentation

# CMP0140

Added 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. It may be set by `cmake_policy()` or `cmake_minimum_required()`. If it is not set, CMake warns, and uses `OLD` behavior.

Note

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