title: Issue trying to build PocketSphinx for Android using the NDK on Windows with Cygwin
body: <p>I'm currently trying to build the PocketSphinx library for Android using the NDK on Windows with Cygwin. I have the PocketSphinxAndroidDemo project code. I also have the pocketsphinx and shpinxbase projects as sub folders of the E:/Development/CMUSphinx folder.</p>
  
  <p>I'm trying to build using ndk-build from the project folder. The Android.mk file in the /jni/ folder of the project looks like this -</p>
  
  <pre><code># Build the native component of the PocketSphinx library for Android.
  
  # You MUST change this to the absolute path of the directory containing
  # sphinxbase and pocketsphinx source code.
  SPHINX_PATH := E:/Development/CMUSphinx
  
  # Copy this Android.mk along with pocketsphinx_wrap.c and the contents of the 'edu' folder
  # built by swig to the jni/ directory of your Android project.

  </code></pre>
  
  <p>When I run the ndk-build command I get the following error:</p>
  
  <pre><code>build-binary.mk:197: *** target pattern contains no '%'. Stop.
  </code></pre>
  
  <p>I can build all the ndk samples just fine. Any clue what's causing this error? Many thanks in advance!</p>
