Okay, I just realised that I don't need a build_depend on python_orocos_kdl
and removing this build dependency makes the error go away.

However, I noticed that in Groovy, both python_orocos_kdl and orocos_kdl
have this cmake config file mentioned above. Since they both exist in
Groovy, I guessed they should both be there in Hydro. However, I am not a
catkin expert, so my guess might well be wrong.
