When using NO_DEFAULT_PATH the lib and include subdirectories will
not be searched by default by find_path and pt-scotch will not be
found outside of the standard path. This commit adds them and now
locally installed versions may supersede the system ones.

DUNE-library
============

DUNE, the Distributed and Unified Numerics Environment is a modular toolbox
for solving partial differential equations with grid-based methods.

The main intention is to create slim interfaces allowing an efficient use of
legacy and/or new libraries. Using C++ techniques DUNE allows one to use very
different implementation of the same concept (i.e. grid, solver, ...) under
a common interface with a very low overhead.

DUNE was designed with flexibility in mind. It supports easy discretization
using methods, like Finite Elements, Finite Volume and also Finite
Differences. Through separation of data structures DUNE allows fast Linear
Algebra like provided in the ISTL module, or usage of external libraries
like blas.

This package contains the basic DUNE common classes.

Dependencies
------------

dune-common depends on the following software packages

- pkg-config
- GNU C, C++ >=4.4
  these might also work:
  icc (C/C++) >= 13.0
  Clang >= 3.2

The following software is recommend but optional:

- MPI (either OpenMPI, lam, or mpich suffice)

For a full explanation of the DUNE installation process please read
the installation notes [0]. The following introduction is meant for
the impatient.
