[Qt-interest] Seeking example qmake project file supporting both 32 and 64-bit targets?

[Ed Sutton]

Does anyone have an example qmake project supporting both 32-bit and 64-bit build targets?

I am trying to evolve an existing qmake project file to supports both a Release32 and Release64 build configurations.  My targets are 32-bit and  64-bit Linux.  I am using the Qt Creator 2.1.

Thanks in advance,
