How to resolve float16 NEON Instructions build errors in ArmRal 21.04?

As shown in the screenshot above， there are always building erros when i use some NEON Instruction in float16_t type(such as vaddq_f16)~

I suspect it is ARMRAL_ARCH_COMPILE_OPTIONS issues which need i to modify "-march=armv8-a+crypto" CACHE INTERNAL ".

I tried many methods and the compilation error still exists。

Can anybody tell me how to resolve this erros?

Thanks a lot!!
