问题 ROS Fuerte I installed on my machine uses opencv 2.2. I would like to use 2.4.9 version just installed. Its location is /home/polar/soft/lib/opencv/opencv-2.4.9/build/lib . How to do that with CMake, please? From my search, it seems that find_library would solve the issue, but was not able to make it work. ===== I include opencv in my cpp codes like this #include <opencv2/core/core.hpp> #include <opencv2/highgui/highgui.hpp> #include <opencv2/opencv.hpp> #include "opencv2/imgproc/imgproc.hpp"
