petsc interface to other packages

[Matteo Semplice <matteo.semplice@unito.it>]

Dear debian-science,

    I am writing some code based on the pestc libraries using a stable 
distribution but, if I create a PetscPartitioner of type 
PETSCPARTITIONERPARMETIS (I have libparmetis-dev and libparmetis4.0 
installed) I get an error message at run-time asking me to "Please 
reconfigure with --download-parmetis." Similarly, when calling 
DMPlexCreateBoxMesh it asks to reconfigure with --download-triangle, 
despite the dev and binary package for libtriangle being installed on my 
machine.

It is expected, or do I have missing link options in my makefile?

If it is not expected to link correctly to parmetis/triangle out of the 
box, I guess that those options are not activated in the standard debian 
build and I am wondering what is the best way to proceed. For example, 
if I downloaded the source package and compiled it locally as described 
in /usr/share/doc/petsc3.7.5-doc/README.Debian.gz, would it find 
automatically the parmetis/triangle from the installed debian package?

Thanks in advance for any suggestion.

    Matteo
