Add CMakeLists.txt (etc...) to sdist

[tlambert03]

#89 added the sdist to pypi, which is great. However, in trying to build this package on conda-forge, I pulled the sdist from pypi and tried to build, but the sdist doesn't contain CMakeLists.txt (and perhaps other things) required to actually build the source.

error

I can use the tar.gz from the github releases for now, but it would be nice to make the sdist fully "build-competent"

ok I think the sdist wants to see a MANIFEST.in file that lists out all the source files to be included. (reference: pytorch/pytorch#52843)

[tlambert03]

manifest.in is one option (the "classic distutils option") for declaring what should get into the sdist, but if you're using setuptools, it gets slightly more complicated. suggest reading this page: https://setuptools.pypa.io/en/latest/userguide/datafiles.html and note the include_package_data and package_data options.

Ultimately, as many times as I've read through those docs, I generally end up doing this by some degree of trial and error. running python setup.py sdist bdist_wheel over and over again, inspecting both the wheel and the sdist, and modifying setup.py and manifest.in until I'm happy.

[toloudis]

I have attempted to do this in the aicspylibczi 3.1.1 build. Still untested but the sdist now has a more complete attempt to bundle all source code. (Gotta figure out how to test this!)
