[Qt-creator] How to set up compilation toochain for msvc

[Matthias Pospiech]

I am using QtCreator from 4.6.2 SDK.

I have installed an older Qt 4.5.2 compiled with msvc 8.0 (2005) which I 
require for a project which
needs a comercial msvc build lib.

Now I want to set up QtCreator to use the msvc toolchain. Thus qmake + 
nmake (+ nmake clean).

I can select in the build configuration the version 4.5.2 and creator 
selects 'Microsoft Visual C++'
But in the buildssteps only qmake is correct. Everything else is still 
mingw32-make.

Why does it not select nmake?

I can overwrite mingw32-make with nmake which leads to a compilation.
But the process of setting it up is strange.
