You're saying this is not needed?
include(${QT_USE_FILE})

That's why there's so many different examples on the web.
Some use it, some don't.  Those who don't have more complex 
CMakeLists.txt files.

Since Qt requires a complex build environment (beyond include 
directories and libraries to link with), the UseQt4.cmake file can be 
used to make it easier.
