Studying your code here. When I try to build I am getting this error

-c module_faces_stubs.cpp)
module_faces_stubs.cpp:10:10: fatal error: 'opencv2/opencv.hpp' file not found
#include <opencv2/opencv.hpp>
         ^~~~~~~~~~~~~~~~~~~~
1 error generated.

and 

In file included from KeyPointDetector.cpp:1:
./KeyPointDetector.h:4:10: fatal error: 'opencv2/face.hpp' file not found
#include <opencv2/face.hpp>
         ^~~~~~~~~~~~~~~~~~
1 error generated.
          cc hera/module_faces/module_faces_stubs.o (exit 1)

and a bunch of others

Where is the project expecting to find opencv2/? how can i tell it where to look?

I cloned opencv in to the project root and built it.

Hey, in theory a system wide installation of opencv should be enough, for example on ubuntu: sudo apt-get install -y libopencv-dev

dune should then be able to find and link the library
