Include pxd in (a) distribution?

I'm looking into packaging neuralcoref, which does a cythonized build against the spacy pxd files.

I've gotten an approach working, where before python -m pip install . in neuralcoref, I sneakily copy all the pxd from the spacy github tarball into the installed spacy (if they aren't already there) do my build, and then clean them up... but that seems pretty gross.

I guess I'm wondering which of the following approaches would be the most robust/least work for everybody:

• layer in the pxd from the source tarball as another source during build of spacy (so neuralcoref only depends on spacy in host and run)
• still grab the source tarball, but add another output here, spacy-cython-source, which neuralcoref can depend on in host, while just depending on spacy in run
• try to get spacy itself to distribute pxd in its source tarball

Thoughts?
