When creating makefiles with qmake one needs to give the target in command line. E.g. $ qmake -config debug or $ qmake -config release For Visual studio projects both targets are generated by just running the qmake command without switches.
Use same warning levels for GCC than in original makefile. Use W4 level for Visual Studio.
