Building the darknet with 'make' in Linux

[Sammytop123]

Hi Rafael,

I'm trying to build your custom darknet repos after having downloaded it with git clone, by using the command 'make' . (running in Linux):
I get the following : "
mkdir -p obj
mkdir -p results
gcc -Iinclude/ -Isrc/ -DOPENCV pkg-config --cflags opencv -DGPU -I/usr/local/cuda/include/ -DCUDNN -Wall -Wno-unknown-pragmas -Wfatal-errors -fPIC -Ofast -DOPENCV -DGPU -DCUDNN -c ./src/gemm.c -o obj/gemm.o
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found
In file included from ./src/utils.h:5,
from ./src/gemm.c:2:
include/darknet.h:25:14: fatal error: opencv2/highgui/highgui_c.h: No such file or directory
25 | #include "opencv2/highgui/highgui_c.h"
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
make: *** [Makefile:85: obj/gemm.o] Error 1
"

How can I resolve this?

Thx
