title: Where are the OpenCV libraries?
body: <p>I'm using Ubuntu and downloaded OpenCV and Eclipse and when i try to configure OpenCV libraries to get rid of <code>undefined reference to XXX</code> I find that <code>opencv-2.4.31\build\lib</code> folder is empty !</p>
  
  <p>I found many question that talk about this problem but the answer was to use a command like that</p>
  
  <pre><code>g++ -o appname appname.cpp `pkg-config opencv --cflags --libs`
  </code></pre>
  
  <p>And that's not what I'm looking for, I need to link the libraries with eclipse.</p>
