[ros-users] Including a package dependency in your personnal packages

[Tully Foote]

Willy,
This would be great for answers.ros.org. It's a question for help with a
straight forward answer, and others might have the same question in the
future and having it easily searchable and tagged on answers.ros.org will
make it more visible in the future.
