title: Building Opencv 2.4.9 with VS 2012, install generates incorrect header files
body: <p>I'm trying to build openCV version 2.4.9 from the git repository. I've followed the instructions to run cmake-gui to build a visual studio solution. I've then built the VS studio solution in both relase and debug mode and then run the install build. </p>
  
  <p>The install build puts all of the compiled libs into the install folder along with the include folder.</p>
  
  <p>The problem is the include folder is completely wrong and missing a number of files. When I add the include folder path to a HelloWorld project it can't find any of the opencv methods classes etc. </p>
  
  <p>Its as though the cmake build process has been corrupted in some way and doesn't properly prepare the include folder with the required header files.</p>
  
  <p>I've tried this for both VS 2010 and VS 2012 cmake configurations and got the same result. Everything compiles fine, the header files in the install directory however aren't right.</p>
  
  <p>Copying header files from a pre-built windows installation sort of work, and i'm confused as to why the build process doesn't result in a similar folder structure of header files.</p>
