I'm struggling to compile marker_mapper which uses aruco lib. This is my settings:

GCC 5.5.0 ubuntu 16.04

Opencv 3.3.1 that comes with ROS (I tried other version of V3)

Aruco 3.0.12

I don't really know what missing.. I've been working with this setting mnay times but I can't figure out the issue why marker_mapper doesn't compile

GAPI is available only in OpenCV 4. Most likely an issue with multiple OpenCV versions on your computer.

@Eduardo Because that package could get compiled with version3 it does exist before V4.. how can I solve that issue of having multiple version? I do specify the exact versions in CMakeLists
