# CMP0122

New in version 3.21.

`UseSWIG` use library name conventions for `CSharp` language.

Starting with CMake 3.21, `UseSWIG` generates now a library using default naming conventions. This policy provides compatibility with projects that expect the legacy behavior.

This policy was introduced in CMake version 3.21. CMake version 3.28.0-rc1 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.
