orocos_kdl_vendor dependency

[mhubii]

Hi! Thought that the orocos_kdl_vendor dependency might be missing here. This might be implicitly linked through kdl_parser, so I think it doesn't cause issues.

I don't think it is needed to make this an explicit dependency.

kdl_parser has it as dependency
https://github.com/ros/kdl_parser/blob/68f4715c678867b4c0a52ea2ec41e53b1f188e7a/kdl_parser/package.xml#L25
and exports it properly
https://github.com/ros/kdl_parser/blob/68f4715c678867b4c0a52ea2ec41e53b1f188e7a/kdl_parser/CMakeLists.txt#L57-L58
