Line 127 in the Makefile: CXXFLAGS+=-msse3 -mpopcnt

Scorpio needs additional libraries to work with neural networks which are all compiled with AVX2 enabled due to performance reasons, but I guess Scorpio itself canbe be compiled without it. If your machine does not have AVX2, you won't be able to use either NNUE or big NN.

Right. I noticed it after I wrote the above message.
