[CMake] QT4 on OSX and Cocoa

[Michael Jackson]

According to this page:

http://qt.nokia.com/downloads/qt-for-open-source-cpp-development-on-mac-os-x

You download EITHER the Carbon OR the Cocoa version. I think you are  
getting confused with actually BUILDING Qt yourself. If you do build  
Qt yourself then you will need to pass the "-cocoa" to the configure  
script in order to build Qt with Cocoa. You would also need to pass  
the proper arch flags in addition so that you build the archs that you  
want to support (i386, ppc, x86_64).

  Once Qt is built and (optionally) installed, CMake will determine  
which option (Carbon or Cocoa) was used when Qt was built and add the  
appropriate compile and linker flags to your build.

Hope that helps.
