#
# - Find SCOTCH include dirs and libraries
# Use this module by invoking find_package with the form:
# find_package(SCOTCH
# [REQUIRED] # Fail with error if scotch is not found
# [COMPONENTS <comp1> <comp2> ...] # dependencies
# )
#
# COMPONENTS can be some of the following:
# - ESMUMPS: to activate detection of Scotch with the esmumps interface
#
# This module finds headers and scotch library.
# Results are reported in variables:
# SCOTCH_FOUND - True if headers and requested libraries were found
# SCOTCH_INCLUDE_DIRS - scotch include directories
# SCOTCH_LIBRARY_DIRS - Link directories for scotch libraries
# SCOTCH_LIBRARIES - scotch component libraries to be linked
# SCOTCH_INTSIZE - Number of octets occupied by a SCOTCH_Num
#
# The user can give specific paths where to find the libraries adding cmake
# options at configure (ex: cmake path/to/project -DSCOTCH=path/to/scotch):
# SCOTCH_DIR - Where to find the base directory of scotch
# SCOTCH_INCDIR - Where to find the header files
# SCOTCH_LIBDIR - Where to find the library files
# The module can also look for the following environment variables if paths
# are not given as cmake variable: SCOTCH_DIR, SCOTCH_INCDIR, SCOTCH_LIBDIR
