-## 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

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

-## catkin specific configuration ##

-## INCLUDE_DIRS: uncomment this if your package contains header files
-## LIBRARIES: libraries you create in this project that dependent projects also need
-## CATKIN_DEPENDS: catkin_packages dependent projects also need
-## DEPENDS: system dependencies of this project that dependent projects also need

-## Declare a C++ library
-# add_library(${PROJECT_NAME}

-## Add cmake target dependencies of the library
-## as an example, code may need to be generated before libraries
-## either from message generation or dynamic reconfigure
-# add_dependencies(${PROJECT_NAME} ${${PROJECT_NAME}_EXPORTED_TARGETS} ${catkin_EXPORTED_TARGETS})
 
-## Declare a C++ executable
-## With catkin_make all packages are built within a single CMake context
-## The recommended prefix ensures that target names across packages don't collide
-# add_executable(${PROJECT_NAME}_node src/wlan_pioneer_node.cpp)
-
-## Rename C++ executable without prefix
-## The above recommended prefix causes long target names, the following renames the
-## target back to the shorter version for ease of user use
-## e.g. "rosrun someones_pkg node" instead of "rosrun someones_pkg someones_pkg_node"
-# set_target_properties(${PROJECT_NAME}_node PROPERTIES OUTPUT_NAME node PREFIX "")

-## Add cmake target dependencies of the executable
-## same as for the library above

-#   DESTINATION ${CATKIN_PACKAGE_INCLUDE_DESTINATION}
-#   FILES_MATCHING PATTERN "*.h"
