I believe we need to use a Depends for things listed in either
Requires or Requires.private for the pkgconfig file to work.

Currently, it looks like nothing in Debian is using that particular
pkgconfig file.
gtk4 looks for it but it fails because the lzo2-dev dependency is not
installed. However, gtk4 then falls back to just using the library
directly without needing the pkgconfig file and that works fine.

Thank you,
