if you don't want the patented algos to be part of your installation, try building with cmake BUILD_opencv_nonfree=OFF (so the nonfree module won't be built)

If the problem is that you don't managed to use SIFT & SURF, it's probably because these algorithms are patented. To use it, add the following line into your main.cpp :

#include <opencv2/nonfree/nonfree.hpp>

And load the nonfree module in your main with this function :

cv::initModule_nonfree(); // to load SURF/SIFT etc.

It should to the trick.
