hi Eric,

thanks for your answer. so, yes I kind of figured out I could do that. But
in fact I was hoping that re-using the existing packagegroup from oe-core
*should* be the right thing to do, instead of re-implementing another one.
and perhaps the packagegroup being called core-qt4e should be restricted to
'core' components, and we could have 1 (or more) additional packagegroups
that could be pulled into images, instead? otherwise what's the point of
having a 'core QT4e packagegroup' if it's not suitable for any real usage?

now, given the current QT4/QT5 stuff, i don't know how relevant this
discussion is.. but i wanted to point out that as a newcomer to this area,
that has been quite confusing!
