What happens when you do make install, make confclean or any other make target doesn't have to do with Qt Creator but with Qt.
In general I wouldn't trust the 'confclean' target that Qt generates, it doesn't quite remove everything also for applications built with Qt/qmake.
The best choice is usually to do shadow builds, then you can just rm -rf the whole build directory and be sure that you get a clean build.
