When building with Helium support, it will be automatically detected by CMSIS-DSP. For Neon, it is not the case and you must enable the option `-DARM_MATH_NEON` for the C compilation. With `cmake` this option is controlled with `-DNEON=ON`. When building with Helium support, it will be automatically detected by CMSIS-DSP.
