Why do you think it wants the SDK installation? Are you getting an error 
message? I have qt-creator built here from sources and have done so for 3 
years, before the SDK was invented.

Yes. That's how both Qt and Qt Creator are themselves developed :-)

There is no extra guidance because this should be quite simple. The commands 
you listed below should have worked. You need to tell us why they didn't.

Qt Creator requires a recent Qt to build. Check that you ran the qmake from 
the Qt 4.8.0 that you've just compiled, not a previous, older version of Qt 
that you might have in your system.
