[ros-users] ROS build customization inconsistency

[Brian Gerkey]

hi Taylor,

The documentation in the wiki is correct.  I fixed the comments in
rosconfig.cmake, r13604 on trunk.

This behavior is not ideal, as noted in the wiki: "NOTE: this ordering
is a little non-intuitive, in that the setting in the package's
CMakeLists.txt is overridden by the settings in the rosconfig.cmake
files."

A related ticket, which led to that note about the non-intuitive
behavior: https://code.ros.org/trac/ros/ticket/566.

	brian.
