You might not have MPI installed on your computer (or MPICH). However, sounds like you are installing this on a personal computer. You should turn off MPI as GROMACS’ internal thread MPI is excellent. You only need to turn on MPI if you are installing this on a cluster where multiple CPUs are used on separated PCs.
If you really need external MPI, the wrapper compiler is usually called ‘mpicc’. So set all the cmake variables to this.
