# - Find PTSCOTCH include dirs and libraries
# Use this module by invoking find_package with the form:
# find_package(PTSCOTCH
# [REQUIRED] # Fail with error if ptscotch is not found
# [COMPONENTS <comp1> <comp2> ...] # dependencies
# )
#
# PTSCOTCH depends on the following libraries:
# - Threads
# - MPI
#
# COMPONENTS can be some of the following:
# - ESMUMPS: to activate detection of PT-Scotch with the esmumps interface
#
# This module finds headers and ptscotch library.
# Results are reported in variables:
# PTSCOTCH_FOUND - True if headers and requested libraries were found
# PTSCOTCH_CFLAGS_OTHER - ptscotch compiler flags without headers paths
# PTSCOTCH_LDFLAGS_OTHER - ptscotch linker flags without libraries
# PTSCOTCH_INCLUDE_DIRS - ptscotch include directories
# PTSCOTCH_LIBRARY_DIRS - ptscotch link directories
# PTSCOTCH_LIBRARIES - ptscotch libraries to be linked (absolute path)
# PTSCOTCH_CFLAGS_OTHER_DEP - ptscotch + dependencies compiler flags without headers paths
# PTSCOTCH_LDFLAGS_OTHER_DEP - ptscotch + dependencies linker flags without libraries
# PTSCOTCH_INCLUDE_DIRS_DEP - ptscotch + dependencies include directories
# PTSCOTCH_LIBRARY_DIRS_DEP - ptscotch + dependencies link directories
# PTSCOTCH_LIBRARIES_DEP - ptscotch + dependencies libraries
# PTSCOTCH_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 -DPTSCOTCH=path/to/ptscotch):
# PTSCOTCH_DIR - Where to find the base directory of ptscotch
# PTSCOTCH_INCDIR - Where to find the header files
# PTSCOTCH_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: PTSCOTCH_DIR, PTSCOTCH_INCDIR, PTSCOTCH_LIBDIR
