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.
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 3.15.2 warns when the policy is not set and uses
OLD behavior. Use the
cmake_policy() command to set it to
OLD behavior of a policy is
deprecated by definition and may be removed in a future version of CMake.
