With this alias it is possible to transparently refer to either the real imported MPI library or to the MPI stub library. this further reduced the need for if statements related to MPI. Some uses of MPI::MPI_CXX remain but they are all in branches of the script code where BUILD_MPI is enabled and thus the imported target will be present.
