After discussing this with Jaroslav Řezník on #fedora-kde a while back I'd
thought this was the way to go, but now I'm not so confident that I correctly
remember his recommendations.  However, I am sure that:
- QtQuick3D needs qmake and Qt sources to build, but does not need to be built
with the rest of Qt4
- Qt4 X11 libs (and other libs) should not need to link against QtQuick3D* libs
- Qt4 X11 libs (and other libs) don't need to link against Qt3D* libs (not sure
if they should for current Fedora policy)

I'd previously attached a qt-quick3d.spec for packaging this separately; I've
just updated it, and a source RPM (missing earlier) can be found at:
http://tomasm.tk/fedorarepo/TMM/SRPMS/qt-quick3d-0-tp1.4.TMM.fc15.src.rpm
I've trialled this with some of the bundled Qt3D and QML demos, and a few
declarative plasmoids importing Qt3D* bits.

When I first filed the review request, I was still hopeful QtQuick3D would
eventually make it into a 4.8 release (and now, I'm not sure if you'd really
want to build this as part of Qt 4.x ever).  The only downsides to a separate
build that I'm aware of are having a second SRPM carrying the 224M qt open
source tarball, and a potential need to rebase some defines or take patches
from the qt4 spec file in the future.
