Have been trying to link Aruco with my Cinder project with no luck, using MacOS and XCode. Using [this](https://forum.libcinder.org/topic/cinder-and-aruco-a-minimal-library-for-augmented-reality-applications-based-on-opencv) as a starting point. Updated the OpenCV block to OpenCV3 and as long as I use Aruco 1.2.5 everything works great, the problem start when I upgrade Aruco to \> 2.0, getting all sorts of errors both in Aruco and OpenCV.

So my question is if anyone here are using Cinder with Aruco 2.0 and if so how?
