While checking for CONFIG_LIBWEBP would be enough to know if webp/encode.h is available 
here as i mentioned in a previous email, it doesn't guarantee that webp/mux.h is available 
as well, so you will need to add webp_mux_h to HEADERS_LIST in configure (the check for 
libwebpmux you already added will enable it if available) and use the resulting define.
