This is way too early to decide this. This is a decision to be made when we're actually ready to try publishing it for regular consumption (not for the people developing it).
Sure. I wasn't expecting concrete answers, just letting people know that
this ought to be considered as well.
It may take us a few months to develop the cmake system, or it may take years, but hopefully not so many years that Ubuntu 20.04
becomes irrelevant.
That feels like a bit of an exaggeration to me. With nothing else taking
my time up, I'm confident I can do the initial work in a week or two.
Unless you mean the total transition, dropping the existing solution and
all that.
