Properly configure your building by changing `config.mk` file. The following options are available:
- **TAG:** Compiler tag (available options: GCC, CLANG, ICC, ONEAPI, NVCC).
- **ISA:** Instruction set (available options: SSE, AVX, AVX2, AVX512).
- **ISA:** Instruction set (available options: SSE, AVX, AVX\_FMA, AVX2, AVX512).
- **MASK\_REGISTERS:** Use AVX512 mask registers (always true when ISA is set to AVX512).
- **OPT\_SCHEME:** Optimization algorithm (available options: lammps, gromacs).
- **ENABLE\_LIKWID:** Enable likwid to make use of HPM counters.
