title: Cannot open include file config.h
body: <p>One of the header files uses</p>
  
  <pre><code>#include &lt;config.h&gt;
  </code></pre>
  
  <p>but I keep getting the error</p>
  
  <blockquote>
    <p>Fatal error C1083: Cannot open include file: 'config.h': No such file or directory</p>
  </blockquote>
  
  <p>and I don't know why. config.h is in the headers folder in the project and when I right-click on it, I can actually open the file too, but I still get this error when building the project.</p>
