linking COLAMD, CCOLAMD, ZLIB

[Andrew Funk]

Hi,

First, thanks John and David for working so quickly on the fix to nnz.
That is working for me now.

So now I am trying to build all the sparse matrix support.  At the end
of configure I get a warning that COLAMD, CCOLAMD, and ZLIB are not
found.  I have installed Ufsparse and zlib, but it's not clear to me the
proper way to tell configure where to find these libraries.  I found
this email in the archives but I'm not sure how to use this information.
Rather than just hacking the Makefile I assume there is a way to specify
at the configuration step where to find the libraries?

Thanks,
Andy

Configure options like

  --with-zlib=/a/dir

are not the right way to tell your compiler where to find the library.

You should use

  CPPFLAGS=-I/a/dir/include LDFLAGS=-L/a/dir/lib configure ...

instead.  Then the value of CPPFLAGS and LDFLAGS are passed to the
compiler when running the tests and you should not have to use
--with-zlib (the configure script will look for zlib by default).
