Hints
^^^^^

The following variables may be set to influence this module's behavior:

``PTSCOTCH_SUFFIX``
  Scotch might be compiled using different integer sizes (int32, int64, long).
  When this is set, the headers and libraries are searched under the suffix
  ``include/scotch-${PTSCOTCH_SUFFIX}`` and ``lib/scotch-${PTSCOTCH_SUFFIX}``,
  respectively.

``SCOTCH_INCLUDE_DIR``
  Include directory where the scotch.h is found.

``PTSCOTCH_INCLUDE_DIR``
  Include directory where the ptscotch.h is found.

``SCOTCH_LIBRARY`` and ``SCOTCHERR_LIBRARY``
  Full paths to the sequential Scotch libraries.

``PTSCOTCH_LIBRARY`` and ``PTSCOTCHERR_LIBRARY``
  Full paths to the parallel PTScotch libraries.
