@Mohammad-Goli I had a really hard time building it. This is basically what I did:

I had to manually build it.
After that, I just followed the instructions and this is what I got, but I found an error at the end.

I had to use this command to be able to import the image:
cat /data/tmp/voxl-mavsdk:v1.2.tar.gz | docker import - voxl-mavsdk:v1.2
But now I can't run it. Hopefully, someone on here can help with this.
