how to set QT Creator to use MSVC++ compiler instead of mingw

how to set QT Creator(opensource) to use MSVC++ compiler instead of mingw ?
I dont see any settings to choose a different compiler rather than mingw.
the only way is vs addin ?

thanks before answers.

see the project tab on the left. There set under "Build Steps" the corresponding spec to qmake.

is there any step by step explaination wiki page for newbies how to setup QT Creator IDE to use MSVC compiler (for x86 and x64)?

I set build steps to :
qmake.exe "C:/Documents and Settings/Administrator/My Documents/qt3/qt3.pro" -spec win32-msvc2008 -r

nothing builds
'cl' is not recognized as an internal or external command,

operable program or batch file.
command failed with exit code 9009


Why this is so hard ?

'cl' isn't in your path. You need to make it so.

Run the visual studio command prompt - that will setup the path correctly, then you can use nmake.

Or, you can include path in environment variable.

Or, you can setup path in batch file before loading QtCreator.

Simples.

cmd :
C:\Documents and Settings\Administrator>cl
'cl' is not recognized as an internal or external command,
operable program or batch file.

another attempt on cmd:
where cl
