I’ve sucessfully installed the dependencies via brew…

@le0pard Thanks so much for the quick reply. The final working configs are

export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/lib:/opt/homebrew/lib/
export CPATH=$CPATH:/usr/local/include:/opt/homebrew/include/

And bumping to > 0.3.1

sudo apt install libwebp-dev

Or just add in bashrc/zshrc

export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/lib
export CPATH=$CPATH:/usr/local/include

This returns the identical running error from above. I tried installing webp on both x86 and arm64 brews too. Same results.

Any ideas?
