title: <CoreFoundation/CoreFoundation.h> not found
body: <p>No matter I use clang, gcc, llvm or cmake, as long as there is this line in the project: </p>
  
  <pre><code>#import &lt;CoreFoundation/Corefoundation.h&gt; 
  </code></pre>
  
  <p>The terminal will show error</p>

  <p>I used to compile objective-c code including this line on terminal well. But the weird problem occurred since my Mac updated to Mojave.</p>
  
  <p>Anyone encounter the same problem? </p>
