Python Compile Mixed C and C++ Extension

Question

I'm attempting to compile libspng with PyBind11 so I can easily convert image data into a numpy array.

The compilation process requires compiling a few C files and then linking them to C++. However, I'm not sure how to do this with Python setuptools. I've so far been compiling all C++ or all C modules in my practice, but on clang, this results in problems when I mix the pybind11 file with the C files.

Is there a simple way that I'm missing to compile and link the C files to C++ within setup.py?

I tried building an extension for libspng, but I wasn't sure how to reference the compiled shared object file which was in the build folder.

Thanks!
