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 3.19.0-rc3 warns when the policy is not set and uses OLD behavior. Use the cmake_policy() command to set it to OLD or NEW explicitly.
