title: DirectXMath and Win8 SDK in VS2010 project
body: <p>I've been working in an engine in Visual Studio 2012 that supports rendering with Direct3D 9 and Direct3D 11. However I'm getting some new people to help with the project and they would prefer to work on Visual Studio 2010 because that's the version they own and use. So I decided to convert the project to be built with VS2010's v100 platform toolset.</p>
  
  <p>I'm getting close to getting it to work but I can't include DirectXMath.h, necessary for the DirectXTK and some utility functions I'm using. It's part of the Windows 8 SDK and included in VS2012, but VS2010 doesn't seem to find it.</p>
  
  <p>Anyone knows how to get it to be included using environment variables so that it works for everybody on the team, and in a way that works on Win7 too?</p>
  
  <p>Thanks.</p>
