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
3.23.3 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.
