Whether this is supported or not is dependent on the LAMMPS version. The correct place to make the update is within

https://github.com/easybuilders/easybuild-easyblocks/blob/develop/easybuild/easyblocks/l/lammps.py#L228

@steenlysgaard Are you planning to follow up on this?

@boegel I have done the change as @ocaisa suggested.

I found the relevant LAMMPS version by looking at this file https://github.com/lammps/lammps/blob/stable_2Aug2023/lib/kokkos/generate_makefile.bash#L182 for different LAMMPS releases

@casparvl Can you submit a test report for this using LAMMPS-29Aug2024-foss-2023b-kokkos.eb on your Icelake system?

@boegelbot please test @ jsc-zen3
