cmake doesn't inform whether UG is seq. or parallel

In former times configure told us, whether UG was compiled with or without MPI. cmake doesn't tell this anymore, which is a bit annoying.

Is this only for the old external UG? Or did I miss a way to compile dune-uggrid differently from the rest of dune?

I didn't try with the new dune-uggrid but I assumed that there must be a way to do this, as we still have to support both versions, due to the fact that you can only run a single UGGrid, when compiled with MPI.

You have to write a check in UseUG.cmake that does basically execute

#ifdef ModelP
return 0;
#else
return 1;
#endf

I don't feel sufficiently familiar with the cmake internals and would have guessed that it is easy for one of our cmake gurus.

I wanted to implement the check and read the code more carefully. It turned out UG_PARALLEL is already set by UseUG.cmake. So nothing left to be done.
