-################################################

-## To declare and build messages, services or actions from within this
-## package, follow these steps:
-## * Let MSG_DEP_SET be the set of packages whose message types you use in
-##   your messages/services/actions (e.g. std_msgs, actionlib_msgs, ...).
-## * In the file package.xml:
-##   * add a build_depend tag for "message_generation"
-##   * add a build_depend and a exec_depend tag for each package in MSG_DEP_SET
-##   * If MSG_DEP_SET isn't empty the following dependency has been pulled in
-##     but can be declared for certainty nonetheless:
-##     * add a exec_depend tag for "message_runtime"
-## * In this file (CMakeLists.txt):
-##   * add "message_generation" and every package in MSG_DEP_SET to
-##     find_package(catkin REQUIRED COMPONENTS ...)
-##   * add "message_runtime" and every package in MSG_DEP_SET to
-##     catkin_package(CATKIN_DEPENDS ...)
-##   * uncomment the add_*_files sections below as needed
-##     and list every .msg/.srv/.action file to be processed
-##   * uncomment the generate_messages entry below
