title: Missing Files error ndk-build
body: <p>I have been trying real hard to get this working but ndk-build always gives me an error when I try to build my project using Cygwin. This is the error I get:</p>
  
  <pre><code>$ /cygdrive/c/work/android-ndk-r8d-windows/android-ndk-r8d/ndk-build
  Android NDK: ERROR:jni/Android.mk:opencv_java: LOCAL_SRC_FILES points to a missing file
  Android NDK: Check that ././../libs/armeabi/libopencv_java.so exists  or that its path is correct
  /cygdrive/c/work/android-ndk-r8d-windows/android-ndk-r8d/build/core/prebuilt-library.mk:43: *** Android NDK: Aborting    .  Stop.
  </code></pre>
  
  <p>I have tried almost everything but the error just does not go away. I am using OpenCV library in my native code to detect faces in an image and return it to the java code.</p>
  
  <p>Anybody who has faced a similar problem or has any tips??</p>
