Must Compile Message and Service Several Times To Work

edit

Folks (sorry for the upper case in advance...they just to make sure people understand those are examples of my code),

What is the proper way to create a CMakeList.txt file that includes messages and services? Every time I create a new group of messages or services and include them in my code, for EXAMPLE,

"my_package_msgs/MessageOrService.h"

it always takes a few "catkin_makes" for my system to recognize the library. Here is my CMakeList file:

cmake_minimum_required(VERSION 2.8.3)
project(message_package_msgs)
find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
  message_generation
  geometry_msgs
  sensor_msgs
)
add_message_files(
  DIRECTORY
    msg
  FILES
    Message_EXAMPLE.msg
)
add_service_files(
  DIRECTORY
    srv
  FILES
    Service_EXAMPLE.srv
)
generate_messages(
  DEPENDENCIES
  std_msgs
  geometry_msgs
  sensor_msgs
)
catkin_package(
  CATKIN_DEPENDS roscpp rospy std_msgs message_runtime geometry_msgs sensor_msgs
include_directories(
  ${catkin_INCLUDE_DIRS}
)

And my package.xml with the build/run only:

  <buildtool_depend>catkin</buildtool_depend>
  <build_depend>roscpp</build_depend>
  <build_depend>rospy</build_depend>
  <build_depend>std_msgs</build_depend>
  <build_depend>message_generation</build_depend>
  <build_depend>geometry_msgs</build_depend>
  <build_depend>sensor_msgs</build_depend>
  <run_depend>roscpp</run_depend>
  <run_depend>rospy</run_depend>
  <run_depend>std_msgs</run_depend>
  <run_depend>sensor_msgs</run_depend>
  <run_depend>message_runtime</run_depend>
  <run_depend>geometry_msgs</run_depend>

What am I missing?
