title: Headers for my static library not found
body: <p>I have a static library iOS project <code>ProjectCore</code>, that I want to include in the project <code>MyProject</code>.</p>
  
  <p>In the library project I set:</p>
  
  <pre><code>PUBLIC_HEADERS_FOLDER_PATH = $(TARGET_NAME)
  </code></pre>
  
  <p>So I end up with the following structure</p>
  
  <pre><code>libProjectCore.a
  ProjectCore (Folder)
  +- ProjectCore.h
  +- ProjectCoreUtil.h
  </code></pre>
  
  <p>In the directory <code>/.../DerivedData/MyProject-xyzabcd/Products/Release-iphoneos/</code>    </p>
  
  <p>Now I setup <code>MyProject</code></p>
  
  <ul>
  <li>Add <code>ProjectCore</code> as a git submodule next to <code>MyProject.xcodeproj</code></li>
  <li>Drag the <code>ProjectCore.xcodeproj</code> to Xcode</li>
  <li>Add the project as a dependency</li>
  <li>Link against <code>libProjectCore.a</code></li>
  <li>I set it's "Header Search Path" to <code>$(BUILT_PRODUCTS_DIR)</code> which should point to the folder above.</li>
  </ul>
  
  <p>Curiously neither of the approaches work:</p>
  
  <pre><code>#import "ProjectCore.h" // With the (Recursive Flag set for the Headers)
  #import &lt;ProjectCore/ProjectCore.h&gt; // The way RestKit does it
  </code></pre>
