Qt usage macro

[Momergil]

QT_VERSION, or pretty much anything from QtGlobal. However, this sort of environment detection is often done outside the program being built by a configure script that sets flags of your choosing if Qt is present and the user has not disabled it.

Hmm, I thought about this possibility... It would be, in this case, something like "#if QT_VERSION > 0x000000"?

Now about what you explained regarding using configuration scripts, I'm not sure I understood the proceeding, but still I see no reason about how could I do that given my context (the header file I'm creating).
