cibuildwheel for Continous Deployment

[ax3l]

Hi @jcfr and @henryiii,

after a few earlier attempts to widen the binary wheel support for urgently needed platforms such as aarch64 #96 #134 #132 and ppc64le, I took a try at it using @joerick's fantastic cibuildwheels project.

You can see my efforts and rationale here: https://github.com/ax3l/cmake-cibuildwheel

Is there general interest to move forward with this?

Personally, I quite urgently (actually since the inauguration of Summit at OLCF three years ago) need ppc64le wheels for users on pre-Exascale supercomputers and Linux aarch64 HPC machines are also there now alongside cloud machines :)

I believe the next release will have support for these platforms, due to @mayeut's fantastic PRs. I think we are just waiting for @jcfr to push the button (and maybe trying to get a few last bits in, like #137). I'd love to use GHA and cibuildwheel in the future, but personally have been short on time to set it up. If you could help with it, I believe it would be very much appreciated (@jcfr can verify).

Oh that's awesome, I'll wait for the final touches then and leave the repo around for now. Great news!

I'm reporting in the meantime some upstream issues, e.g. this macOS delocate issue: matthew-brett/delocate#105

@ax3l,

I like the idea very much. So much that I opened a draft PR to start working on this !
