Using addons with openFrameworks on Raspberry Pi

@elliot wrote:

I'm trying to compile a project on a Raspberry Pi with an addon that is in the openFrameworks/addons directory.
I created the addons.make file in the project directory and added ofxOpenCv to the first line.

I then in my ofApp.h file added the include for ofxOpenCv:

#pragma once
#include "ofMain.h"
#include "ofxOpenCv"

class ofApp : public ofBaseApp{

When trying to compile the project with make -j2 -s results in an error relating to not being able to find the ofxOpenCv directory.

Not sure if there is a certain way I need to link the addon to the project.

Any help would be great.

Here is the compilation error:
