#
# - Find PASTIX include dirs and libraries
# Use this module by invoking find_package with the form:
# find_package(PASTIX
# [REQUIRED] # Fail with error if pastix is not found
# [COMPONENTS <comp1> <comp2> ...] # dependencies
# )
#
# PASTIX depends on the following libraries:
# - Threads, m, rt
# - MPI
# - HWLOC
# - BLAS
#
# COMPONENTS are optional libraries PASTIX could be linked with,
# Use it to drive detection of a specific compilation chain
# COMPONENTS can be some of the following:
# - MPI: to activate detection of the parallel MPI version (default)
# it looks for Threads, HWLOC, BLAS, MPI and ScaLAPACK libraries
# - SEQ: to activate detection of the sequential version (exclude MPI version)
# - STARPU: to activate detection of StarPU version
# it looks for MPI version of StarPU (default behaviour)
# if SEQ and STARPU are given, it looks for a StarPU without MPI
# - STARPU_CUDA: to activate detection of StarPU with CUDA
# - STARPU_FXT: to activate detection of StarPU with FxT
# - SCOTCH: to activate detection of PASTIX linked with SCOTCH
# - PTSCOTCH: to activate detection of PASTIX linked with SCOTCH
# - METIS: to activate detection of PASTIX linked with SCOTCH
#
# This module finds headers and pastix library.
# Results are reported in variables:
# PASTIX_FOUND - True if headers and requested libraries were found
# PASTIX_LINKER_FLAGS - list of required linker flags (excluding -l and -L)
# PASTIX_INCLUDE_DIRS - pastix include directories
# PASTIX_LIBRARY_DIRS - Link directories for pastix libraries
# PASTIX_LIBRARIES - pastix libraries
# PASTIX_INCLUDE_DIRS_DEP - pastix + dependencies include directories
# PASTIX_LIBRARY_DIRS_DEP - pastix + dependencies link directories
# PASTIX_LIBRARIES_DEP - pastix libraries + dependencies
#
# The user can give specific paths where to find the libraries adding cmake
# options at configure (ex: cmake path/to/project -DPASTIX_DIR=path/to/pastix):
# PASTIX_DIR - Where to find the base directory of pastix
# PASTIX_INCDIR - Where to find the header files
# PASTIX_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: PASTIX_DIR, PASTIX_INCDIR, PASTIX_LIBDIR
