message(QT_CONFIG = $$QT_CONFIG)

However, qmake is a strictly imperative environment so it will print the 
value of QT_CONFIG at the time you hit the message() call. The value may 
be changed later.

You can run qmake -d -d -d and it will dump a (very verbose) log showing 
exactly when variables change. It includes the final value of all the 
variables at the end.
