Set up graphicsmagick on local


I’m trying to setup graphicsmagick on my local instance and am having trouble getting it set up. So far, I’ve only got as far as:

apt-get install graphicsmagick

What other steps can I take to get this installed and working on my local instance? I’m trying to add image thumbnails for PDF files using graphicsmagick.

Local setup:
Web server: nginx
PHP Version: 7.3.2
MySQL version: 5.5.60
WP: multisite
