mpicxx and icpx?

[vanderwb]

I've just installed the 2022.1 release of both the Base and HPC toolkits, and I've noticed that mpicxx does not seem to support icpx:

[16:22] intel$ mpicxx -cxx=icpc -o test hello.cpp
[16:22] intel$ mpicxx -cxx=icpx -o test hello.cpp
Error: unsupported compiler name 'icpx'.
Check -cxx=<compiler_name> command line option and I_MPI_CXX='icpc' and MPICH_CXX='' variables.

mpiicpc does seem to support both, but many application build systems expect to use the generic mpicxx wrapper. Meanwhile, the problem does not exist for C code, which makes me think that this was an oversight:

[16:21] intel$ mpicc -cc=icc -o test hello.c
[16:21] intel$ mpicc -cc=icx -o test hello.c

A quick inspection of the wrapper itself shows that the case statement does not have a statement for icpx.
