-## Declare ROS messages, services and actions ##
-################################################
-
-## 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
-## * add every package in MSG_DEP_SET to generate_messages(DEPENDENCIES ...)
-
-## Generate messages in the 'msg' folder
-# add_message_files(
-# FILES
-# Message1.msg
-# Message2.msg
-# )
-
-## Generate services in the 'srv' folder
-# add_service_files(
-# FILES
-# Service1.srv
-# Service2.srv
-# )
-
-## Generate actions in the 'action' folder
-# add_action_files(
-# FILES
-# Action1.action
-# Action2.action

-
-## Generate added messages and services with any dependencies listed here
-# generate_messages(
-# DEPENDENCIES
-# std_msgs # Or other packages containing msgs
-# )
-
-################################################
-## Declare ROS dynamic reconfigure parameters ##
-################################################
-
-## To declare and build dynamic reconfigure parameters within this
-## package, follow these steps:
-## * In the file package.xml:
-## * add a build_depend and a exec_depend tag for "dynamic_reconfigure"
-## * In this file (CMakeLists.txt):
-## * add "dynamic_reconfigure" to
-## find_package(catkin REQUIRED COMPONENTS ...)
-## * uncomment the "generate_dynamic_reconfigure_options" section below
-## and list every .cfg file to be processed
-
-## Generate dynamic reconfigure parameters in the 'cfg' folder
