gazebo msgs

edit

I want to publish a gazebo_msgs ( topic) NOT service using .cpp code as a node I wrote the code, but I dont know what to add in the Cmakelist in these sections:

  find_package(catkin REQUIRED COMPONENTS
  nav_msgs
  roscpp 
   ...../// what should I write here 
 }

// second

catkin_package(
#  INCLUDE_DIRS include
#  LIBRARIES rosaria_nav
 CATKIN_DEPENDS message_runtime nav_msgs roscpp sensor_msgs ***gazebo_msgs***
 // is it right ????? 
 #  DEPENDS system_lib
)

// third

generate_messages(
 DEPENDENCIES
 geometry_msgs  sensor_msgs nav_msgs visualization_msgs gazebo_msgs
)

// forth

I added the following

add_executable(SetModelState src/SetModelState.cpp)
add_dependencies(SetModelState ${PROJECT_NAME}_gencfg ${PROJECT_NAME}_generate_messages_cpp)  
target_link_libraries(SetModelState
 ${catkin_LIBRARIES}
 ${Boost_LIBRARIES}
)

//fifth in the .cpp file ( the node ), I added the following library

 #include <gazebo_msgs/SetModelState.h>
