title: Build "ImageTargets" shared library-Vuforia sample application
body: <p>I followed the procedure according to the site: <a href="https://developer.vuforia.com/resources/dev-guide/step-3-compiling-running-vuforia-sample-app" rel="nofollow">https://developer.vuforia.com/resources/dev-guide/step-3-compiling-running-vuforia-sample-app</a>.</p>
  
  <p>I tried to build ImageTargets shared library through cygwin but the displayed message is:</p>
  
  <pre><code>$ ndk-build
  Android NDK: Could not find application project directory !
  Android NDK: Please define the NDK_PROJECT_PATH variable to point to it.
  /cygdrive/c/Users/Dimitris/Desktop/ANDROID/adt-bundle-windows-x86/android-ndk-r8e/build/core/build-local.mk:130: *** Android NDK: Aborting    .  Stop.
  </code></pre>
  
  <p>I can assure you that no empty character is to the path of my project directory.</p>
  
  <p>I have located ImageTargets project into the folder : <code>C:\Users\Dimitris\Desktop\ANDROID\adt-bundle-windows-x86\samples</code></p>
  
  <p>So i ran the commands:</p>
  
  <p><code>$ cd C:/Users/Dimitris/Desktop/ANDROID/adt-bundle-windows-x86/samples</code></p>
  
  <p>and </p>
  
  <p><code>$ ndk-build</code></p>
