# CMP0122

Added 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. 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.
