title: Missing includes during compilation (Cocos2d-x 3.1 + XCode 5.1.1)
body: <p>It appear that I can't solve this trivial looking problem...</p>
  
  <p>I downloaded Libcocos2d-x, ran the dependancies script:</p>
  
  <pre><code>$&gt; ./download-deps.py
  </code></pre>
  
  <p>who filled the "external/" folder with all the third party headers.</p>
  
  <p>Then I generated a project using:</p>
  
  <pre><code>$&gt; ./cocos new -p "xx.xx.xx" -l cpp -d "xx/xx/xx"
  </code></pre>
  
  <p>This worked fine.</p>
  
  <p>But when I try to compile this new born project, the only thing I get are includes errors.
  I tried to fix them manually, but nothing to do, even when "curl.h" get included, he keep asking for "curl/curl.h" and vice versa.
  And curl is just the start of it, it looks like all the .h of the cocos project are missing:</p>
  
  <pre><code>/Users/xx/Desktop/Dev/aa/cocos2d/extensions/assets-manager/AssetsManager.cpp:27:10: 'curl/curl.h' file not found
  /Users/xx/Desktop/Dev/aa/cocos2d/cocos/platform/CCSAXParser.cpp:30:10: 'tinyxml2.h' file not found
  etc...
  </code></pre>
  
  <p>If anyone has any clue about this I'm listening.</p>
