-Subject: [PATCH] make tests succeed when MPI is disabled
-
-When MPI is not available or explicitly disabled with the CMake build
-option -DCMAKE_IDSABLE_FIND_PACKAGE_MPI=TRUE, some tests were unable to
-build.
-
-The tests created from solverfactorytest.cc.in and part of
-scalarproductstest.cc use Dune::OwnerOverlapCopyCommunication which is
-defined behind `#if HAVE_MPI` and is thus not available in a non-MPI
-build. I've thus disabled those tests when MPI is unavailable.
-
-The matrixmarkettest did not work without MPI, as it contained some code
-using the wrong template parameters when HAVE_MPI was not set. Those
-template paramters have been fixed now.
-
-I've confirmed, that after my changes `make build_tests` succeeds to
-build all tests and that those tests run without failure.
