Hello. I'm new for ROS. I have a question about how to use and implement a stack.
I've already read all of the tutorials of ROS. But I couldn't find the way to implement an arbitrary stack.
For instance, I'd like to use an OpenCV with ROS.(My PC has NOT been installed OpenCV) In this case, first I install ROS(electric). Second, I get the stack, vision_opencv via internet. Next, what should I do?
Sorry for my beginner's question. Thanks in advance.
