[Qt-creator] CMake support change in master branch

[Mathias Hasselmann]

Sure you are not giving in to a vocal minority? I very much liked 
QtCreator's cmake support so far.
I'll very much miss the possibility to set CMake options with proper UI 
from within QtCreator.
Hopefully support for passing "--target=<Current Executable>" stays? 
Turnaround cycles will become terrible without.

Ciao

Any CMake command line argument can be provided, so you can now ask for warnings to be enabled/disabled or whatever else is supported by CMake.

The sole truth about CMake configuration is the CMakeCache.txt file. This also means that swiching build directories will result in a loss of configuration, something that we tried to avoid earlier. I think overall this is an acceptable cost, considering that Creator did not do a great job at it in the first place:-)
