CMP0086 — CMake 3.19.6 Documentation

# CMP0086

New in version 3.14.

`UseSWIG` honors `SWIG_MODULE_NAME` via `-module` flag.

Starting with CMake 3.14, `UseSWIG` passes option `-module <module_name>` to `SWIG` compiler if the file property `SWIG_MODULE_NAME` is specified. This policy provides compatibility with projects that expect the legacy behavior.

The `OLD` behavior for this policy is to never pass `-module` option. The `NEW` behavior is to pass `-module` option to `SWIG` compiler if `SWIG_MODULE_NAME` is specified.

This policy was introduced in CMake version 3.14. CMake version 3.19.6 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.
