cicd: mypyc

[romintomasetti]

The goal of this PR is to add mypyc to speedup things "for free".

I had to change a bit the CMakeApiType protocol because mypyc does not like class variables in a dataclass:

• Dataclasses incorrectly include ClassVar annotated attributes as fields mypyc/mypyc#1122

@madebr Could you please have a look?

[madebr]

Everything looks super! Thank you very much!

What kind of speed-up are you talking about with a project using cmake-file-api?

[romintomasetti]

I haven't made any measurement but I expect that:

• https://www.github.com/uliegecsm/reprospect

will benefit. We use cmake_file_api quite extensively in the tests.

@madebr If you make a release, we'll be able to test if it behaves well in https://www.github.com/uliegecsm/reprospect 😉

I think the current release process is not correct and should be changed: it's failing.
It currently builds a source and binary wheel (sdist bdist_wheel).
mypyc causes the binary wheel to contain platform- and python version specific binaries, whereas before it was platform agnostic (aka plain python sources).

What do you suggest to do?

[romintomasetti]

I think it is fine to have many wheels. It will be handled nicely if I remember well...

I suggest to install the dev requirements, see #32 😉

Haha, yes, that's a requirement I was missing :)
But running bdist_wheel on my dev machine, dist/cmake_file_api-0.0.8.7-cp314-cp314-linux_x86_64.whl is created.
This means it won't run on macOS, Windows and other python versions.

[romintomasetti]

My understanding is that you are not breaking anything because it will also produce the source-based wheel that will be uploaded alongside any mypyc-based wheel on PyPi. And pip install will figure out which one to pick.

See for instance https://pypi.org/project/reprospect/#files. Along with the sources, there are different compiled versions.
