Should we emit a warning (which probably will be ignored) or better refuse to build with "5.0" <= QT < "5.4" ?
I don't think so, the indication INSTALL file should be enough in that case.
From my POV, if user selects QT5, we should use it.
Agreed. In addition, from my POV, it is better if Qt5 for big enough values of 5 are selected as default, so that one does not have to select it explicitly.
