[ros-users] rosmake CMakeLists.txt rosversion test

[Brian Gerkey]

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 .

	brian.
