You'll need to clone kde-build-metadata as 'dependencies' there as
well. The script "setup-env.sh" should take care of cloning in the
various repos which are needed.

You are correct. For Windows, we have a lack of licenses - so cannot
setup any virtual machines to provide this service.
For Mac, we'd need corresponding physical systems due to the way that
is licensed.

I can arrange access to one of the current CI nodes once you have
something workable. If you need any pointers on the scripts, or have
patches, please let me know.
