failure to build on arm

[brettowe]

while attempting to build this I get the below linking error:

[ 98%] Linking CXX executable SMHasher

I can reproduce this problem with this command

git clone https://github.com/rurban/smhasher.git --recursive ; cmake -S smhasher/ -B build-smhasher/ ; cmake --build build-smhasher

which was commit 0f6bf14 at the time

this gives:
