Could not find the required component 'Float32' in ROS Service

edit

I am trying to send float values from python client to C++ server using ros service call. I am getting this error message:

Could not find the required component 'Float32'. The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found. CMake Error at /opt/ros/indigo/share/catkin/cmake/catkinConfig.cmake:83 (find_package):

Could not find a package configuration file provided by "Float32" with any
  of the following names:

    Float32Config.cmake
    float32-config.cmake

  Add the installation prefix of "Float32" to CMAKE_PREFIX_PATH or set
  "Float32_DIR" to a directory containing one of the above files.  If
  "Float32" provides a separate development package or SDK, be sure it has
  been installed.

Here is my CmakeList.txt:

cmake_minimum_required(VERSION 2.8.3)
project(pr2_package)

find_package(catkin REQUIRED COMPONENTS
  moveit_core 
  moveit_ros_planning 
  moveit_ros_planning_interface 
  Float32
  roscpp
  rospy
  std_msgs
  message_generation
)


add_executable(pr2_package_1 src/gripper.cpp
)
target_link_libraries(pr2_package_1 ${catkin_LIBRARIES})
add_dependencies(pr2_package_1 ${PROJECT_NAME}_generate_messages_cpp)



## Generate messages in the 'msg' folder
 add_message_files(
   FILES
   Pose.msg
 )

## Generate services in the 'srv' folder
 add_service_files(
   FILES
   PoseSend.srv
 )


## Generate added messages and services with any dependencies listed here
generate_messages(
   DEPENDENCIES
   std_msgs
   Float32
 )

Here is my Pose.msg file:

Here is my srv file:

Float32 a
Float32 b
Float32 c
Float32 d
