Personally, I prefer the split tarballs, as individual build times are 
much shorter, apart from qtweb* which are horrendous.
It also make it possible to upgrade qtbase, while keeping the other 
components unchanged. Old components should work with newer foundations.
Bear in mind that some things are classed as experimental, others are 
deprecated or obsolete and will not be updated after qt-5.5.

I have just pushed a bunch of commits which add lots of kde5-frameworks 
libraries.
The files KDE_DEPENDS and KDE_FUNCTIONS should give some clues about 
building things against qt5.
Plasma stuff will follow next week, when 5.3.0 is available.
Then come the apps, whis where the real conflicts start.

Major apps such as digikam and calligra should be available by June.
Digikam is virtually complete, while calligra  already builds with qt5.
Kdenlive, konversation, kate and gwenview have been released, as have 
most of the games and education stuff.
I have spells for all of these,

kdepim is still in progress.

I have been building all this qt5/kde5 stuff for a long time, and now 
my systems are pure qt5.

I think that having multiple qt5 versions would be a major headache.
I agree that the qmake build system is seriously broke, which cause all 
the self conflicts.


Be aware that qt-4.8.7 should be released in a few days. That will be 
the last qt4 version. I would like to take that opporunity to make it 
install to /opt/qt4, which is how I have been using it locally for a 
long time.
