Hi guys! I've found my project doesn't compile after update from cryptopp-5.6.5 to cryptopp-8.0.0. This change <https://github.com/weidai11/cryptopp/commit/4e3a1ea962d8f8cc58b97d2dd59554479a2b2db9> (config.h:598) seems to be the reason, as it assumes that every ARM processor has Arm Neon architecture extension. But, as in my case, that's not true. Fix attached solved my case.
