ci: Cache and install dependencies and libraries

Note: We define CMAKE_PREFIX_PATH for OBS Studio here, which should normally (https://cmake.org/cmake/help/latest/variable/CMAKE_PREFIX_PATH.html#variable:CMAKE_PREFIX_PATH) be filled by the project itself. This is technically non-standard behavior, and may be remedied in the future by OBS Studio.
