I am a Heroku buildpack that installs Cairo and its dependencies (Pango, Pixman, FreeType, HarfBuzz, and giflib) into a dyno slug.
When used with heroku-buildpack-multi, I enable subsequent buildpacks / steps to link to this library.
You'll almost certainly want to use this in conjunction with one or more additional buildpacks. Heroku supports using multiple buildpacks for an app.
heroku buildpacks:add --index 1 https://github.com/mojodna/heroku-buildpack-cairo.gitThis uses Docker to build against Heroku stack-image-like images.
makeArtifacts will be dropped in dist/. See Dockerfiles for build options.
