 | |
| # - 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
