I have gone through the instructions for running cmake a number of times, and it works for the basic modules that are included in Opencv, but when it comes to the old 'nonfree' modules, in the Extra Modules git download , it won't compile to be able to run a program that has #include "opencv/xfeatures2d.hpp"

https://github.com/Itseez/opencv_contrib ^This is the place to download the extra modules

This what Terminal gives me when I try to 'make'

smithj :surf_matcher smithj$ make

#include "opencv2/xfeatures2d.hpp"

when building the opencv libs, did you run a make install ? this should have copied all the headers to your install/include folder.

I am also having the same error, and I did make install. But when I run my project it says xfeatures2d.hpp file not found.
