I downloaded source files from
now in src/misc_utilities
I can see classifychar.cpp
but it requires:
include "opencv2/highgui/highgui.hpp"
include "opencv2/imgproc/imgproc.hpp"
so I downloaded OpenCV2
source but inside it I cant find highgui/highgui.hpp
instead its in \modules\highgui\include\opencv2
so I changed it its absolute path. Now I cant find utility.h
and support/ut8f.h
