Setting the compiler wrapper in CMake instead of in CC and CXX is recommended, but only works for recent CMake versions (one configuration I tested requires CMake 3.20 for the intel compiler). With 9.3.1 deal.II supports setting CXX=mpicxx again, so only do the above when a setting in candi.cfg is specified. Works around dealii#202 and fixes feature introduced in dealii#159

Note that this doesn't work with 9.3.0 in some cases but we are working on a 9.3.1 release. |

@tjhei yep. But this PR was on master (which is master deal.II now) |
