title: Cmake is Unable to Configure Project for Visual Studios 10 amd64
body: <p>I am trying to get CMAKE to create a project for msvc 10 express edition for x64 architecture.  I have both MSVC 2010 Express and Windows SDK 7.1 installed.  </p>
  
  <p>If I start CMake Normally I can create a 32 bit project, however it fails to make a 64 bit project.  I have also Tried starting CMAKE from within the Windows SDK Command Prompt (cl cmd maps to x64 version) however It still fails with the following.</p>
