When testing on macOS, the command `swig_add_library("mytarget")` creates a library `libmytarget.so` instead of `libmytarget.dylib`. Subsequently, the library is not found by dotnet and the swig-generated `DllImport` statements. With the small change in PR https://gitlab.kitware.com/cmake/cmake/-/merge_requests/7659, everything works correctly. Tested with cmake `3.24.0`.
