title: How to fix .pch file missing on build?
body: <p>When I build my c++ solution in Visual Studio it complains that the xxxxx.pch file is missing. Is there a setting I am missing to get the pre-compiled headers back?</p>
  
  <p>here is the exact error for completeness:</p>
  
  <pre><code>Error   1   fatal error C1083: Cannot open precompiled header file: 'Debug\xxxxx.pch': No such file or directory
  </code></pre>
