Re: [ros-users] rosmake CMakeLists.txt rosversion test

hi Ben,

What you're doing is reasonable, given that there's not currently
support for doing it any better. However, you really want to be
testing the version of actionlib, not ros; the two evolve
independently.

There's currently no way to do that, so I've ticketed myself to add a
package/stack version query in rosbuild:
https://code.ros.org/trac/ros/ticket/3010 .
