- [X] This fundable has not been submitted yet.
Motivation
While conda packages offer more packaging flexibility for shared libraries, wheels are sometimes more convenient for some Python-adjacent end-users. There are a number of examples out there following this strategy:
- https://github.com/Unidata/netcdf4-python/blob/master/.github/workflows/cibuildwheel.yml
- https://github.com/pygraphviz/pygraphviz/pull/537
- https://github.com/openmm/openmm-wheels

Expected result
An installable project that can simplify the involved workarounds, possibly available as a Github Actions action so folks can easily create their wheels on CI.

Conda-press goal is similar but the road to get there is quite different. In the examples above the plan is to use conda-forge non-Python dependencies to build compliant wheels. Conda-press converts conda packages to wheels and breaks the compliance in a few places. That is one of the reasons it was abandoned. It was a hard sell for the ecosystem. Providing community curated dependencies, on the other hand, is easier to get folks into to.
