hplip 3.20.9 compile fails on Ubuntu 18.04 server with "/usr/bin/ld: cannot find -lImageProcessor"

Trying to install hplip 3.20.9 on a Raspberry Pi 3B running Ubuntu Server 18.04.
After choosing the configuration options from the hplip-3.20.9.run script, the make command fails with "error: 'make' command failed with status code 2"
Tried running the installer with "python3 ./installer -g" and capturing the debug output.
The make process is failing with the following output:

I've tried this script on DietPi, Debian 10.6, and Ubuntu 18.04 Server without success.
Any suggestions would be welcome.

Thanks.
