Great.  We'll resolve it that way then.  It's already used in other mpi 
packages where mpirun is invoked explicitly.
I didn't catch that adios4dolfinx was invoking mpi tests internally 
inside its tests.

I don't thing it's an issue. DEB_BUILD_OPTIONS=parallel is more about 
the build itself (triggering make -j8 for example) than about testing 
mpi execution.
