title: define NDK_ROOT in cocos2DX mutiplatform game environment
body: <p>I have just started working with cocos2dx android and I am following wonderful tutorial of <a href="http://www.raywenderlich.com/33750/cocos2d-x-tutorial-for-ios-and-android-getting-started" rel="nofollow noreferrer">http://www.raywenderlich.com/33750/cocos2d-x-tutorial-for-ios-and-android-getting-started</a> . Now, I have successfully run my first hello world demo project by following this link. I also set environment parameters:</p>
  
  <pre><code>NDK_ROOT_LOCAL="/MY ANDROID NDK PATH/"
  
  ANDROID_SDK_ROOT_LOCAL="/MY ANDROID SDK PATH/"
  </code></pre>
  
  <p>I followed tutorial perfectly as given in it, still I am facing problem while running my project second time, means I have to export DNK_ROOT every time from terminal to run my project &amp; it's really tired and seemed not working for my further implementation..  and while I run project it says please define NDK_ROOT though I already define </p>
  
  <h1>second thing</h1>
  
  <p>I also manually define these variables in my .bash profile (create-android-project.sh) this way</p>
  
  <pre><code>NDK_ROOT_LOCAL = "/MY ANDROID NDK PATH/"
  
  ANDROID_SDK_ROOT_LOCAL = "/MY ANDROID SDK PATH/"
  </code></pre>
  
  <p>What am I missing in setting up this?</p>
