Revert "Remove BUILD_IN_SOURCE option for Qt on non-windows systems as well"

following:

    .obj/debug/qmutex.o
    .obj/debug/qmutex_mac.o

    .obj/debug/qmutex.o
    .obj/debug/qmutex_mac.o

    .obj/debug/qmutex_mac.o
duplicate symbol 'QMutexPrivate::~QMutexPrivate()' in:

    .obj/debug/qmutex_mac.o
duplicate symbol 'QMutexPrivate::wait(int)' in:
