title: Where are the opencv2 include files?
body: <p>I'm struggling to find the include files that should be in a directory names "opencv2"! I've downloaded OpenCV-2.4.0.tar.bz2 from <a href="http://sourceforge.net/projects/opencvlibrary/files/latest/download?source=files" rel="noreferrer">here</a> and extracted the files and ran cmake, which seemed to build the library successfully.</p>
  
  <p>The problem is that under the "include" directory for "opencv2" there seem to be tons of header files missing. The only header file there at the moment is "opencv.hpp", which includes a whole set of other files which aren't there. Does anyone have any idea where I can get these files from?</p>
