OpenCV 2.1 (which has been out since several months now, I think) comes with
FindOpenCV.cmake. What Alex wrote on the website refers to that.

Gilles reported the same problem to me a few days back. It looks like you're
using Mandriva. Mandriva (unlike most other distros) ships OpenCV split into
multiple packages. You probably need to install a package named something
like "opencv-samples".

 Ok. I'll try to fix it. But I'm not very knowledgeable about CMake
configuring, can you tell me what to do?
