Comment 0 for bug 1164508

Continuation from bug #1135336 (as is bug #1164504). If both Qt 5 and Qt 4 are installed, both would be usable for developers at the same time. However, Qt Creator only auto-configures the system default one into use. The non-default Qt can be configured into use manually via Tools -> Options -> Qt Versions, but ideally Qt Creator should auto-configure all the system Qt:s.
