[ros-users] rosmake CMakeLists.txt rosversion test

Is there an easy way to test for the ROS version in a CMakeLists.txt
file? For example, when using actionlib, two different sets of commands
must be used to generate the action messages. I came up with this CMake
way to do it, but it is rather clumsy and I am not exactly sure of the
version numbers. It would be nice if rosbuild provided simple macros
for this.



execute_process(COMMAND rosversion ros

                RESULT_VARIABLE rosversion)

IF (${rosversion} GREATER 1.05)

message("CTurtle")

ELSE (${rosversion} GREATER 1.05)

message("BoxTurtle")

ENDIF (${rosversion} GREATER 1.05)



Thanks,
