we are now checking for different locations of parmetis.h. This makes it possible us the
scotch parmetis implementation (see FS#1370).

we now check for METIS_PartGraphKway, which a symbol we are actually using and which
is in the implementation of scotch (see FS#1370)

Conflicts:
	cmake/modules/CheckCXX11Features.cmake

Avoid upper case commands.

They do not find a package but check for a feature.
This avoids false warnings about not found packages.
Merged FindCXX11Conditional.cmake and FindCXX11Features.cmake.

The patch from ...fce82c7d5ee5 broke the script.
This is the intended behavior.

As decided on the developer meeting in Aachen, we support (but do not
rely on) the C++11 keyword constexpr. This patch adds an m4-check for
constexpr and a header (cxx11.hh) defining a macro DUNE_CONSTEXPR either
as constexpr or empty (depending on the compiler support for it). It is
then used in FieldVector and FieldMatrix on size, rows, and cols.

Before this commit it matched e.g. "test1" and failed finding the directory "test".

Previously, a variable (found) was only initialized in one branch
of an if statement but used later on in any case. This patch makes
sure that is initialized in both branches.

This fixes FS#1352.
Thanks to Bernd Flemisch for the hint.

[BuildSystem][autotools] Add FinalizeHeadercheck.cmake to installation file list of cmake/scripts instead of incorrect cmake/modules.

[BuildSystem][CMake] Add FinalizeHeadercheck.cmake to installation file list of cmake/scripts instead of incorrect cmake/modules.

Previously the CMAKE variable was not set if no options file was used. This
fixes this.

Exclusion from the headercheck can be achieved in a CMakeLists.txt
file via the following macros:

exclude_from_headercheck(list...)
exclude_dir_from_headercheck()
exclude_all_but_from_headercheck(list...)

When not excluded, all headers matching dune/*.hh or src/*.hh
will be checked.

Unlike with autotools, make headercheck can only be called on the
toplevel module directory and then run on all module headers. In
contrast to autotools, CMake will cache the results and rerun only
checks on changed headers.

The current algorithm for hash combining behaves very poorly when hashing
multiple short streams of small integers like (0,1,1,0,x) that only differ
by a single large number x. These objects appear frequently in PDELab's ordering
framework, and the resulting bad hash distribution really hurts the performance
of the unordered containers in PDELab.

This patch switches to an algorithm that is inspired by CityHash (see the source
code comment) and has proven to be much more robust in testing.

With this patch it is possible to request CMake for building
by setting USE_CMAKE=yes in an option file.

In one of the latest patches I introduced a bug which caused
the --builddir option of dunecontrol to not make any effect.
This patch fixes this.

There is no obvious reason to quote one variable and not the other.
If more CMP0019 warnings are found, they have to be fixed in the same
way.
This was only an issue with CMake 2.8.11 or newer.
