title: OpenCV 2.4 : problems with includes in Qt in windows
body: <p>I am not a C++ master (far from that actually), I try to setup an OpenCV + Qt project. I have downloaded the last release of OpenCV. I did nothing more with that (if I understand well, everything is pre-built, so I just have to add the path to the libs in my .pro file).</p>
  <p>I added the path to the include folder /opencv/include</p>
  <p>That should work that way, since the includes in cv.h, for example, are like that :</p>
  <h1>include &quot;opencv2/core/core_c.h&quot;</h1>
  <p>However, when I browse through my opencv folder, opencv2 is empty, there is no core folder in it, nor anything else, actually there is just a header file, opencv.h .</p>
  <p>I noticed that all my include are spread into several folders, under the module folder... what should I do??</p>
  <p>Thank you very much!</p>
