# - Try to find SCOTCH
# Once done this will define
#
# SCOTCH_FOUND - system has found SCOTCH
# SCOTCH_INCLUDE_DIRS - include directories for SCOTCH
# SCOTCH_LIBARIES - libraries for SCOTCH
# SCOTCH_VERSION - version for SCOTCH
#
# Variables used by this module, they can change the default behaviour and
# need to be set before calling find_package:
#
# SCOTCH_DEBUG - Set this to TRUE to enable debugging output
# of FindScotchPT.cmake if you are having problems.
