# - Try to find Eigen2 lib
#
# This module supports requiring a minimum version, e.g. you can do
# find_package(Eigen2 2.0.3)
# to require version 2.0.3 to newer of Eigen2.
#
# Once done this will define
#
# STORMEIGEN2_FOUND - system has eigen lib with correct version
# STORMEIGEN2_INCLUDE_DIR - the eigen include directory
# STORMEIGEN2_VERSION - eigen version
