title: opencv_contrib unable to compile program (even though build was successful) with OpenCV 3.0.0 beta
body: <p>I installed the latest version of opencv (OpenCv 3.0.0 Beta). I downloaded the opencv_contrib module and built it with opencv by doing a cmake (by following the instructions in the readme <a href="https://github.com/itseez/opencv_contrib" rel="nofollow">https://github.com/itseez/opencv_contrib</a>). The build happened successfully. I wrote a simple program which uses creates a BasicFaceRecognizer model. However, when I compile my program I get the following error message
  fatal error: opencv2/face.hpp: No such file or directory
   #include"opencv2/face.hpp"
  The code is very simple. Just wanted to check if it compiles before proceeding further.</p>
  
  <pre><code>#include"opencv2/opencv_modules.hpp"
  #include"opencv2/face.hpp"
  using namespace cv;
  using namespace cv::face;
  int main()
  {
      Ptr&lt;BasicFaceRecognizer&gt; model = createEigenFaceRecognizer();
      return 0;
  }
  </code></pre>
