Switched to append a full string of "-Xarch_x86_64 -maes" instead of " -Xarch_x86_64" "-maes", for example. Now cmake correctly appends -Xarch_x86_64 to each x64 specific compile option, removing the error caused in recent clang releases:

clang++: error: unsupported option '-msse4.1' for target 'arm64-apple-darwin23.5.0'
