Windows resolves DLLs using search paths and names by default, so there’s no need to do anything special other than put it in the right place and it will be found. (There are other complexities, but for a properly-integrated environment these can be made to work. But this is one of the core problems when you cobble together an environment with pip but without actually doing the system integration work. Conda helps by making properly built packages work together, but some effort is still required when custom-built dependencies conflict.)
