The latest Cineware SDK explicitly asserts macOS support in its documentation, but Assimp's C4D importer only works with Windows MSVC targets. Let's improve its portability by refactoring importer code to not depend on MSVC-only data types and quirks, and add support for linking against the universal macOS static libraries provided in the Cineware SDK.
Note that the C4D importer still cannot support Linux platforms because Maxon does not provide the necessary precompiled Cineware libraries for that platform. Windows MinGW targets are also out of the question as the MinGW toolchain uses compiled libraries in a different format.
