The EWWW Image Optimizer Plugin is unable to generate WebP image due to the following error:

Attempting to run cwebp manually shows that it is in fact not installed in the image.

EWWW Image Optimizer uses jpegtran, optipng, pngout, pngquant, gifsicle, and cwebp. You are missing: jpegtran, optipng, gifsicle. Please install via the Settings Page or the Installation Instructions.
