GDAL 3.5.0 fails to compile with `PROJ 6 symbols not found` #30

Closed edmorley closed 2 years ago

Trying to compile GDAL 3.5.0 using a new build script based on those already in this repo, results in:

$ make build-heroku-20

It seems proj is now required at build time too: https://github.com/OSGeo/gdal/issues/1352

Vendoring like this buildpack already does for libkml is one option, but then we'll end up with duplicate proj installs, given we build it separately too.

I also spot-checked 3.4.2 and 3.0.4, and they are affected too, so I presume this affects any 3.x GDAL version.
