The current idea is to use vcpkg to automate building from sources (yes, even 
on non-Windows). Whether we continue down that path will depend on how well 
it's working.

We'll have yet one more LTS Qt before 6.0: 5.15. I also expect that to be even 
longer term supported than the other ones. My point was only about 6.0 itself: 
when you do take that plunge, I recommend a full upgrade of everything else 
to.

No, it won't be required. This is just what I recommend.
