ROS package compatibility with ROSDEP

[peci1]

The provided ROS packages didn't play well if one wanted to install dependencies using `rosdep`.

I fixed it at least to work:

However, it seems to me there are lots of unnecessary build dependencies (mainly OpenCV), and maybe some run dependencies are missing. However, I'm not going to investigate more unless I really need to.
