As a distro packager, I think this is definitely the way to go. Tracking 
what package any individual file comes from is what the package manager is 
for. This is also how it works for manpages, .desktop files, etc.

Why would we need to invent yet another directory? QT_INSTALL_DOCS in Fedora 
is currently /usr/share/doc/qt5, I think that is perfectly fine. It is also 
versioned, so you do not get, e.g., kdelibs4 apidocs in the Qt 5 Assistant, 
or the other way round.

I think you should just use the existing QT_INSTALL_DOCS directory and stick 
to it, no need to reinvent the wheel and break compatibility.
