How to change Accelerator?

[kusnezoff-alexander]

How can one change the Acc (CPU/CPU-OMP/CPU-Threads/CUDA)?

Eg simply changing Dalpaka_ACC_CPU_B_SEQ_T_SEQ_ENABLE=ON to -DALPAKA_ACC_CPU_B_OMP2_T_SEQ_ENABLED=ON doesn't work for me:

mkdir -p build && cd build && \
cmake ../all -DALPAKA_ACC_CPU_B_OMP2_T_SEQ_ENABLED=ON -DCPM_SOURCE_CACHE=~/.cache/cpm && \
cmake --build . -j --target KitGenBenchExamplePlainMalloc KitGenBenchExampleSimpleMallocMC
```

Typo:

< -DALPAKA_ACC_CPU_B_OMP2_T_SEQ_ENABLED=ON
> -DALPAKA_ACC_CPU_B_OMP2_T_SEQ_ENABLE=ON

For CUDA you probably have to add alpaka_ACC_GPU_CUDA_ONLY_MODE because we use CUDA-specific code in kernels.
