Thanks for the nice work and blog posts. The thing that is missing are the files that allow cmake to actually execute the commands:
These files come along with the installation of OpenCV and PCL, and in the case of OpenMP it should come with CMake.
If CMake can't find the location of "FindOpenCV.cmake" and the others, you can help it by defining the OPENCV_DIR parameters (like "cmake -DOPENCV_DIR=location/of/findopencv.cmake/")
Yes, I know. On Ubuntu 12.10 it doesn't come with opencv from the repository. I checked with:
apt-file list libopencv-dev
So, if it's not too much, maybe it's nice to add them to a "cmake" directory to make it work across a range of platforms.
