Clearly, there is a tangled dependency web. OSX apps have menus, the the QML
menu stuff inherits from the QMenu stuff. There may be widgets that just aren't
severable, however, I agree that things should be more piecemeal because if you
don't you wind up with this. You may just want to do static linking if min
binary size is what you are after.
With some of the blog posts about the upcoming 5.9 and later, it looks like the
differences between the systems will be minimized.
