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,
