title: Missing D3DX definitions from updated project
body: <p>I need to update a old June DX10 application. </p>
  
  <p>My original setup was such that i had the include files and libraries for DX10 as part of my repo. This compiles and runs fine, but causes hundred of warning on macro redefinitions when i'm compiling it on Win10 using VS2015 with the VS2013 compiler. </p>
  
  <p>I wanted to fix the warrnings and so i consulted <a href="https://msdn.microsoft.com/en-us/library/windows/desktop/ee663275%28v=vs.85%29.aspx#sdk_vs11" rel="nofollow">this blog post from microsoft</a>. After following the steps there (Modifying the project’s VC++ directories and changing my includes), the project won't compile as it's doesn't know what a lot of classes and definitions i used are... For example D3DMATRIX gives me syntax error/undeclared identifier.</p>
  
  <p>What is the correct course of updating my project?</p>
