At a high level, that sounds reasonable, but I don't think this is 
necessarily the best solution for all cases. It it useful to hard-depend 
on, for example, QtTest and QtWidgets in the root, when they are only 
required by autotests (and one may choose not to build them)?

While I am in favour of only depending on what's actually required for 
the build (which in my opinion is in the spirit of the individual 
frameworks thing), I am not too bothered either way.

My main motivation is to establish how things should be, and send a 
consistency patch. That will make it a little bit easier for packaging too.
