How to compile?

1. Go to the OpenCV website and use 
   http://opencv.willowgarage.com/wiki/InstallGuide
   to compile & install a working copy of OpenCV
2. Check out the infos at
   http://opencv.willowgarage.com/wiki/Getting_started
   This is more or less what I did

Tried and tested with Microsoft Visual C++ 2010 Express
