CMP0086

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 3.15.7 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.
