Problem with linking OpenCV to Webots(Ubuntu)

Question

I've just started using Webots and I want to include OpenCV for a project. I read that in order to do this, I should modify the makefile of my controller. So, I made a simple controller in which the robot goes forward and it is just fine. I opened then the makefile and I added the first two lines:1

I have installed OpenCV 3.2 on my system and I confirm it with:2

Building my controller I see the following: 3

I also tried the

#include "opencv2/highgui.hpp"

but it said

fatal error: opencv2/highgui.hpp: No such file or directory

Do you have any ideas? Thank you in advance.

Can you check by the command ```pkg-config --modversion opencv```? To be sure ur opencv exist correctly? — Yunus Temurlenk, Feb 21 '20 at 18:41
I've tried it, it says the same error: fatal error: opencv2/highgui/highgui.hpp : No such file or directory. I think something happens with pkg-config in the makefile but I don't understand why. Thank you anyway. — loukasp96, Feb 22 '20 at 09:36
