# - Find METIS include dirs and libraries
|
|
# Use this module by invoking find_package with the form:
|
|
# find_package(METIS
|
|
# [REQUIRED] # Fail with error if metis is not found
|
|
# )
|
|
#
|
|
# This module finds headers and metis library.
|
|
# Results are reported in variables:
|
|
# METIS_FOUND - True if headers and requested libraries were found
|
|
# METIS_INCLUDE_DIRS - metis include directories
|
|
# METIS_LIBRARY_DIRS - Link directories for metis libraries
|
|
# METIS_LIBRARIES - metis component libraries to be linked
|
|
#
|
|
# The user can give specific paths where to find the libraries adding cmake
|
|
# options at configure (ex: cmake path/to/project -DMETIS_DIR=path/to/metis):
|
|
# METIS_DIR - Where to find the base directory of metis
|
|
# METIS_INCDIR - Where to find the header files
|
|
# METIS_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: METIS_DIR, METIS_INCDIR, METIS_LIBDIR
