I use a .pro snippet something like this:

RCC_BINARY_SOURCES += ../assets/opengl-assets.qrc
asset_builder.commands = $$[QT_HOST_BINS]/rcc -binary ${QMAKE_FILE_IN} 
-o ${QMAKE_FILE_OUT}
asset_builder.depend_command = $$[QT_HOST_BINS]/rcc -list 
$$QMAKE_RESOURCE_FLAGS ${QMAKE_FILE_IN}
asset_builder.input = RCC_BINARY_SOURCES
asset_builder.output = $$OUT_PWD/../assets/${QMAKE_FILE_IN_BASE}.qrb
asset_builder.CONFIG += no_link target_predeps
QMAKE_EXTRA_COMPILERS += asset_builder

Just add your qrc files to the RCC_BINARY_SOURCES variable. Then in your 
C++ application you can load the binary resource file with:

bool success = QResource::registerResource( assetPath );

 From then on, use it as normal.

Cheers,

Sean
