How to install cwebp on mac

I followed this Stack Overflow question.

Step 1

/usr/sbin/softwareupdate –install-rosetta –agree-to-license

Step 2

arch -x86_64 /bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)”

Step 3

arch -x86_64 brew install cweb
arch -x86_64 brew install webp

Install them one at a time.
