Support pure C/CPP extensions

[vhdirk]

Hi!

I'm trying to port a cython extension using hatch-cython. But contrary to all examples, it's composed completely in C, rather than pyx/pxd/py files. This is the one I'm trying to port: https://github.com/hbldh/b2ac/blob/master/setup.py

Do you have any suggestions/ides on how you would do this?

If I add c to the precompiled extensions and just replace the 'sources' parameter for setuptools Extension in the generated setup.py, it seems to work. Does the order of the files in 'sources' matter?

Hey! No problem - there's actually a test case for this (or closest to). You'll want to set up a build hook first, and then you’ll want to point hatch to the build hook. You should then be able to utilize the c/c++ source in Cython to develop the bridge code between the two (eg). If you're trying to build the bridge (ie no cython at all) automatically, I'm open to this as a FR - granted though, there would still need to be something to point to for the namespace imports / externs else we are opening the case for full global emissions.
