Do not know how to Install cwebp on phone. See Linux and windows. Nothing for Android. Assuming no root needed? Tasker can launch the ss file. I cannot see how to set android permissions to execute for file. Extensions don't matter in Linux. Compile has never worked for me outside of ahk or basic. Never enough help for c or Linux compile.
