btw currently i have opencv 2.4.13
When I was complie the code, it displays :/home/lenovo/simple_slam_loop_closure/DBoW2/build/dependencies/src/DLib/include/DVision/BRIEF.h:32:28: fatal error: opencv2/core.hpp: No such file or directory
#include <opencv2/core.hpp>
I find the hpp file in /usr/include/opencv2/core/, so I change #include <opencv2/core.hpp> to #include <opencv2/core/core.hpp>. But it show the above errors.
