title: opencv : unresolved external symbol
body: <p>I know this question is <a href="https://stackoverflow.com/questions/16038602/unresolved-external-symbol-with-opencv">all over</a> the <a href="https://stackoverflow.com/questions/9173452/unresolved-external-symbol-error-in-opencv">place</a>, but still the magic stick of adding the library directories to the project properties is not working for me.</p>
  
  <p>I followed the <a href="http://docs.opencv.org/trunk/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html" rel="nofollow noreferrer">tutorial for Visual Studio</a> (2013 I have here) and the <a href="http://docs.opencv.org/trunk/doc/tutorials/introduction/windows_install/windows_install.html#windowssetpathandenviromentvariable" rel="nofollow noreferrer">environment variable setup</a> for <strong>opencv 3.0 beta</strong>.</p>
  
  <p>And it's the same code on the <strong>Test it!</strong> section. Here's the header of build output in vs:</p>

  <p>The rest of the log is the same. I've used the <strong>opencv\build\x86\vs12</strong> directory contents for the <strong>lib</strong> and <strong>bin</strong> directories. I'm blindly using the <code>/MDd</code> option in <strong>C/C++->Code Generation->Runtime Library</strong> option. What's wrong?</p>
