# Module that checks whether SuperLU is available and usable.
# SuperLU must be a version released after the year 2005.
#
# Variables used by this module which you may want to set:
# SUPERLU_ROOT Path list to search for SuperLU
#
# Sets the follwing variable:
#
# SUPERLU_FOUND True if SuperLU available and usable.
# SUPERLU_MIN_VERSION_4_3 True if SuperLU version >= 4.3.
# SUPERLU_POST_2005_VERSION True if SuperLU is from post-2005
# SUPERLU_WITH_VERSION Human readable string containing version information.
# SUPERLU_INCLUDE_DIRS Path to the SuperLU include dirs.
# SUPERLU_LIBRARIES Name to the SuperLU library.
