Error "FindEigen3.cmake" during install kinetic on RPi

edit

hi all

first: marry christmas

second : I'm not skilled about install a so large enviroment|software ... so I followed the wiki : install Kinect on raspberry http://wiki.ros.org/ROSberryPi/Installing ROS Kinetic on the Raspberry Pi and at point 3.3 Building the catkin Workspace I have got this error

CMake Error at CMakeLists.txt:24 (find_package): 
 By not providing "FindEigen3.cmake" in CMAKE_MODULE_PATH this project has 
 asked CMake to find a package configuration file provided by "Eigen3", but 
 CMake did not find one. 

 Could not find a package configuration file provided by "Eigen3" with any 
 of the following names: 

   Eigen3Config.cmake 
   eigen3-config.cmake

I've read many posts, but it is unclear for me which cmakelist.txt edit and how to fix it.
