Yes, the webp terminal is built only if the configure script finds the
required support libraries.
If they are not found it prints a message in the summary output,
for instance:

  libgd-based png jpeg gif sixel: yes (with animated gif)
 cairo-based pdf png  : yes
 webp                 : no (requires cairo, pango, libwebp, libwebpmux)
 lua/TikZ             : yes
 wxt                  : yes
 Qt                   : yes (qt5)

The webp and webpmux libraries are available directly from Google
    https://developers.google.com/speed/webp/download
They are included as standard packages in my linux distro (Mageia);
I do not know which other distros package them.
