title: Fatal Error C1083: Cannot Open Include file: 'tiffio.h': No such file or directory VC++ 2008
body: <p>I got this error when I tried to compile an application that includes the <code>tiffio.h</code> header.</p>
  
  <p>For the record, the <code>tiffio.h</code> is located at: </p>
  
  <p><code>C:\Program Files\GnuWin32\include</code></p>
  
  <p>I <em>have</em> set that directory to be included in the 'Projects' and 'Solution' Visual C++ directories, as shown in the image located here.</p>
  
  <p>What am I missing?</p>
