Dear Maintainer,


If a user creates a DUNE module with the duneproject script on Debian sid with
the package libscotchmetis-dev install, then running CMake will fail in this
module:

-- Found PTScotch: /usr/lib/x86_64-linux-gnu/libscotch.so (found version
"7.0.1")
-- Looking for METIS_PartGraphVKway
CMake Error: The following variables are used in this project, but they are set
to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake
files:

build/test/tester/build/CMakeFiles/CMakeTmp

According to bug #1007830 this is because METIS_PartGraphVKway is in metis v3
but
the default version used in v5. Therefore we might need to change
/usr/share/dune/cmake/module/FindMetis.cmake
such that it uses libmetisv3.so.

Explanation copied from #1007830:

scotch 7.0.1 has just been uploaded to unstable.  It provides some metis (and
parmetis) compatibility which opm-grid is using.

The scotch metis compatibility version can be selected via metis.h
with define variable SCOTCH_METIS_VERSION. If not set then
SCOTCH_METIS_VERSION=5 is applied, i.e. metis v5.

>From scotch v7, compatibility libraries are provided for both metis v3
and v5 (libscotchmetisv3.so, libscotchmetisv5.so).  For default metis
