CMP0078 — CMake 3.17.2 Documentation

# CMP0078

`UseSWIG` generates standard target names.

Starting with CMake 3.13, `UseSWIG` generates now standard target names. This policy provides compatibility with projects that expect the legacy behavior.

The `OLD` behavior for this policy relies on `UseSWIG_TARGET_NAME_PREFERENCE` variable that can be used to specify an explicit preference. The value may be one of:

- `LEGACY`: legacy strategy is applied. Variable `SWIG_MODULE_<name>_REAL_NAME` must be used to get real target name. This is the default if not specified.
- `STANDARD`: target name matches specified name.

This policy was introduced in CMake version 3.13. CMake version 3.17.2 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.
