# FindEigen.cmake - Find Eigen library, version >= 3.
#
# This module defines the following variables:
#
# EIGEN_FOUND: TRUE iff Eigen is found.
# EIGEN_INCLUDE_DIRS: Include directories for Eigen.
# EIGEN_VERSION: Extracted from Eigen/src/Core/util/Macros.h
# EIGEN_WORLD_VERSION: Equal to 3 if EIGEN_VERSION = 3.2.0
# EIGEN_MAJOR_VERSION: Equal to 2 if EIGEN_VERSION = 3.2.0
# EIGEN_MINOR_VERSION: Equal to 0 if EIGEN_VERSION = 3.2.0
# FOUND_INSTALLED_EIGEN_CMAKE_CONFIGURATION: True iff the version of Eigen
# found was built & installed /
# exported as a CMake package.
#
# The following variables control the behaviour of this module:
#
# EIGEN_PREFER_EXPORTED_EIGEN_CMAKE_CONFIGURATION: TRUE/FALSE, iff TRUE then
# then prefer using an exported CMake configuration
# generated by Eigen over searching for the
# Eigen components manually. Otherwise (FALSE)
# ignore any exported Eigen CMake configurations and
# always perform a manual search for the components.
# Default: TRUE iff user does not define this variable
# before we are called, and does NOT specify
# EIGEN_INCLUDE_DIR_HINTS, otherwise FALSE.
# EIGEN_INCLUDE_DIR_HINTS: List of additional directories in which to
# search for eigen includes, e.g: /timbuktu/eigen3.
#
# The following variables are also defined by this module, but in line with
# CMake recommended FindPackage() module style should NOT be referenced directly
# by callers (use the plural variables detailed above instead). These variables
# do however affect the behaviour of the module via FIND_[PATH/LIBRARY]() which
# are NOT re-called (i.e. search for library is not repeated) if these variables
# are set with valid values _in the CMake cache_. This means that if these
# variables are set directly in the cache, either by the user in the CMake GUI,
# or by the user passing -DVAR=VALUE directives to CMake when called (which
# explicitly defines a cache variable), then they will be used verbatim,
# bypassing the HINTS variables and other hard-coded search locations.
#
# EIGEN_INCLUDE_DIR: Include directory for CXSparse, not including the
# include directory of any dependencies.
# Called if we failed to find Eigen or any of it's required dependencies,
# unsets all public (designed to be used externally) variables and reports
# error message at priority depending upon [REQUIRED/QUIET/<NONE>] argument.
