It might be getting set with an environment variable, or a default value
somewhere. There are a lot more components to this than is revealed from the
Check the man pages for your compiler to see what CPU architectures it
supports. It appears you’re building it on a Mac, and in that case it is
either using gcc (which the version of gcc on a mac is older than the
aforementioned arm cpu), or more likely is using LLVM, which I am not familiar
what CPU architectures it supports. The man pages should cover that though.
One quick way to test the theory is to run the newer binary and see how many
cores are being used.
