I have already awared of it and used  -DNPARTITION to build CHOLMOD without 
METIS.

Pherhaps you noticed the following, but I would dare to say it for myself.

What I would like to say is as follows:
In the suitesparse page, the cholmod with metis is described.
Making the cholmod library with metis itself and use it users' own program is 
not problem.

However if they use the cholmod library with metis for building octave,
thier action will be comfilct to the current GPL.

My proposal is to make the document like 'ReadmeSuitespase' and 
describe this problem in it.
