) 16 # 17 # This module finds headers and metis library. 18 # Results are reported in variables: 19 # METIS_FOUND - True if headers and requested libraries were found 20 # METIS_INCLUDE_DIRS - metis include directories 21 # METIS_LIBRARY_DIRS - Link directories for metis libraries 22 # METIS_LIBRARIES - metis component libraries to be linked 23 # 24 # The user can give specific paths where to find the libraries adding cmake 25 # options at configure (ex: cmake path/to/project -DMETIS_DIR=path/to/metis): 26 # METIS_DIR - Where to find the base directory of metis 27 # METIS_INCDIR - Where to find the header files 28 # METIS_LIBDIR - Where to find the library files 29 # The module can also look for the following environment variables if paths 30 # are not given as cmake variable: METIS_DIR, METIS_INCDIR, METIS_LIBDIR 31 32 #============================================================================= 33 #
