hmmm, I should have included a snippet of the relevant part. Here it is

# METIS, optionally used by CHOLMOD

# If you do not have METIS, or do not wish to use it in CHOLMOD, you  
must
# compile CHOLMOD with the -DNPARTITION flag.  You must also use the
# "METIS =" option, below.

# The path is relative to where it is used, in CHOLMOD/Lib, CHOLMOD/ 
MATLAB, etc.
# You may wish to use an absolute path.  METIS is optional.  Compile
# CHOLMOD with -DNPARTITION if you do not wish to use METIS.
METIS_PATH = ../../metis-4.0
METIS = ../../metis-4.0/libmetis.a

# If you use CHOLMOD_CONFIG = -DNPARTITION then you must use the  
following
# options:
# METIS_PATH =
# METIS =
