[eigen] Official FindEigen.cmake?

[Cedric Doucet <cedric.doucet@xxxxxxxx>]

Hello,

I would like to be able to find Eigen with CMake.

To do that, I need to call the find_package function for Eigen, but there is no FindEigen.cmake file in my version of CMake.

Is there an official CMake file to do that, or a non-official one which is preferred?
