Impossible to make a plugin with the tutorial

edit

EDIT : I finally created the plugin. For people who would like to create a plugin for rqt with the tutorial, here is part of my code.

My directories are : in /catkin_ws/src/rqt_mypkg : src, plugin.xml, package.xml, CMakeLists.txt, include, script, setup.py

In /catkin_ws/src/rqt_mypkg/src/rqt_mypkg : my_plugin.cpp, my_plugin.ui, receveur.cpp

In /catkin_ws/src/rqt_mypkg/include/rqt_mypkg : my_plugin.h

package.xml :

<?xml version="1.0"?>
<package>
  <name>rqt_mypkg</name>
  <version>0.0.0</version>
  <description>The rqt_mypkg package</description>

  <export>
<rqt_gui plugin="/home/pierre/catkin_ws/src/rqt_mypkg/plugin.xml"/>

  </export>
</package>

My CMakeLists.txt :

cmake_minimum_required(VERSION 2.8.3)
project(rqt_mypkg)

## Find catkin macros and libraries
## if COMPONENTS list like find_package(catkin REQUIRED COMPONENTS xyz)
## is used, also find other catkin packages
find_package(catkin REQUIRED COMPONENTS
  rospy
roscpp
roslint
  rqt_gui
  rqt_gui_cpp
  rqt_gui_py
std_msgs
genmsg
)

## System dependencies are found with CMake's conventions
 find_package(Qt4 COMPONENTS QtCore QtGUi REQUIRED)

include(${QT_USE_FILE})

 catkin_python_setup()


roslint_cpp()

## Generate added messages and services with any dependencies listed here
 generate_messages(
   DEPENDENCIES
   std_msgs  # Or other packages containing msgs
