Qt with Visual Studio 2010

I've downloaded the source and compiled it from the VS command prompt using nmake. I've also installed the VS 2010 addin. However, now when I go to Qt -> Options -> Add and find the newly Qt compiled binaries, it says:

"Qt in the given path was compiled with MinGW."

No I haven't. What's this all about? I've use开发者_如何学God "-platform win32-msvc2010" to configure too.

EDIT:

just to add, the path I was browsing for was like: QTDIR\qt\

It sounds like you have the binaries from the Qt sdk on the machine and it's finding those instead of the ones you compiled.
