-# - Try to find Eigen3 lib
-#
-# This module supports requiring a minimum version, e.g. you can do
-# find_package(Eigen3 3.1.2)
-# 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
