-# This module supports requiring a minimum version, e.g. you can do

-# to require version 3.1.2 or newer of Eigen3.
-#
-# Once done this will define

-#  EIGEN3_FOUND - system has eigen lib with correct version
-#  EIGEN3_INCLUDE_DIR - the eigen include directory
-#  EIGEN3_VERSION - eigen version
