Hello Tom & Jasem
I have managed to get there. I can now see RollOffino in Ekos on Stellarmate on my RPi.
I found that a "build" directory was created in the "Projects" when building the Indi portion of the process. I had to use that "build" directory for the cmake of the Indi-rolloffino.
The command had to be: $ cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug ~/Projects/indi-3rdparty/indi-rolloffino
Now to get the Arduino and Ekos to play. I think I have a connection but not quite the relay control and sensor inputs yet.
Thanks again for all the help you guys have provided.
