[gdal-dev] Python Wheels for gdal

[Idan Miara]

Hi all,

I'm wondering how difficult it would be to build the windows wheels with
the windows builder on the github CI
<https://github.com/OSGeo/gdal/blob/master/.github/workflows/windows_build.yml>,
.
I imagine we would need to install all the supported python versions to
build all the pyd files.
We might want to build a win32 version if anyone still cares about those.

Does someone have a different idea ? maybe a standalone builder script? but
then someone would need to run it manually I guess.
