/* ERROR/WARNING messages:
E: Invalid Kokkos command-line args
Self-explanatory. See Section 2.7 of the manual for details.
E: GPUs are requested but Kokkos has not been compiled for CUDA
Recompile Kokkos with CUDA support to use GPUs.
E: Kokkos has been compiled for CUDA but no GPUs are requested
One or more GPUs must be used when Kokkos is compiled for CUDA.
E: Must use Kokkos half/thread or full neighbor list with threads or GPUs
Using Kokkos half-neighbor lists with threading is not allowed.
E: Illegal ... command
Self-explanatory. Check the input script syntax and compare to the
documentation for the command. You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.
