# Default make builds both original darknet, and its CPP equivalent darknet-cpp
# make darknet - only darknet (original code)

# CPP version supports OpenCV3. Tested on Ubuntu 16.04

# OPENCV=1 (C++ && CV3, or C && CV2 only - check with pkg-config --modversion opencv)
# When building CV3 and C version, will get errors like
# ./obj/image.o: In function `cvPointFrom32f':
# /usr/local/include/opencv2/core/types_c.h:929: undefined reference to `cvRound'
