How to integrate code-generators with catkin
I'm trying to integrate some code-generators into catkin. In contrast to the ROS message generator, they produce .h and .cpp files. So where are those files supposed to go? The ROS message generator writes the generated .h files into devel/include/xyz/. But where would the .cpp files go in this case? Most code generators are not too happy about writing .h and .cpp to different locations.
