Cmdstan 2.21.0 - Can't make clean-all after adding MPI make/local flags

[wds15]

This is the same as this one:

Building cmdstan 2.20 with mpi enabled on Linux

Thank you. Just in case somebody has a system similar to mine (actually it worked on systems from two different universities): module load gcc/5.3.0 module load openmpi/3.1.4 git clone … as in https://github.com/stan-dev/cmdstan/wiki/Getting-Started-with-CmdStan in make/local STAN_MPI=true CXX=mpicxx TBB_CXX_TYPE=gcc make build

Can you please update our wiki on MPI - it’s currently lacking the hint that TBB_CXX_TYPE must be set manually… or file an issue to Stan-math where this would need to be fixed.

Thanks.
