In theory there were no API changes, but it looks like something broke
in the new .cfg dependency generation.

That error message seems to be sucked in by cmake as a list of
dependencies, and I have created #4092 to track the problem.

In terms of fixing your problem, I would suggest using the SensorLevels
from driver_base. I intend to deprecate the ones in dynamic_reconfigure.
I'm not sure why this is breaking and have created #4093 to remind
myself to figure it out.
