Thanks for the submission, @doronbehar

Unfortunately, I am absolutely refusing this PR. Vendoring has been discussed at length on the issue tracker, and I remain yet to be convinced that the users and maintainers of Imager gain anything from an alternative strategy.

You are, of course, free to maintain a fork. You should, however, be advised that I will not be considering the impact of build system rework on any forks - the users of Imager remain my primary concern.

@tdewey-rpi could you please share with me a link to a discussion about vendoring? I didn't find any when I searched vendor before submitting the PR.

A search for "vendoring" finds a big discussion in #924

Also, could you please maybe review the 1st commit of this PR? It is related but should be separated from the anti-vendoring changes.

It might be better to submit that as a separate PR?
