> What are the dependencies that I can just install with apt? I don't use conda or any of the other package managers listed in the readme. Any help is appreciated.

I would suggest to look at the gdal packaging in Ubuntu or Debian. There are "make-depends" in the dsc files or in debian/control.
My entry page is 
https://tracker.debian.org/pkg/gdal 
dsc file are linked via an icon in the "versioned links" on the left side. 
debian/control can be reached via "browse source code" on the right side.
