Yes. You must call cmake from the Visual Studio Command Prompt (either in the 
Windows start menu or from the IDE).
Additional, there is no gain in trying to find libraries that come with the 
compiler or system when they are always there. Additionally, the compiler 
itself knows where to find them.
