[eroux]

let's try to use nuitka in github workflows to build for windows and OSX

@eroux: I believe this has already been done. This may be closed.

There's some build automation yes, but it doesn't result in packages that work on Intel macOS yet... I'll close this as soon as the packages work well

[iamazeem]

Right.
The artifacts contain a main.build folder with source, object, and other files.
Apparently, that's unused. That may be removed. Will reduce the overall package size.

Also, currently, the build is only triggered on tag.
I've earlier suggested to add workflow_dispatch also to trigger manual builds.
Commented the same on 4cdd078: 4cdd078#r151881549

Uploading of build artifacts to release is also missing.
That may be added as well if no manual step is involved.

Hey @iamazeem,

Yep exactly the build folder shouldn't be in the package and the release automated, I'll get to that after I'm done with the notarizing.
