Bear with me to come back to this :)

How do the cmake files factor into this, and qtchooser? In other words, how does this work for projects that don't expect you to invoke qmake by hand (or IDE) but are based on cmake instead? Do Qt5's cmake files have built-in support for qtchooser (i.e. they use -qt=qt5), are they rewritten during the installation procedure, or does one have to point cmake to the correct qmake executable?

Thanks,
