Review comment:
In my opinion, we shouldn't have problem. Because we should only have one
kwargs[option] even we have multiple C modules. So, even we enter into multiple
times, we only append duplicate `find_include_path()` results. But we could
only do it once to avoid duplicate includes. My updated code uses one
`cache_kwargs` to make it sure we only enter this condition once, if you have
good suggestion, you could comment it again.
