The only reference to METIS::METIS that I can find in cmake config
files is from libopm-grid-dev, in
/usr/lib/x86_64-linux-gnu/cmake/opm-grid/opm-grid-targets.cmake 
and
/usr/lib/x86_64-linux-gnu/cmake/opm-grid/opm-grid-config.cmake

Does libopm-grid-dev need to be patched to get the METIS::METIS target
defined (or removed)?
