This is a Heroku buildpack for vendoring the ImageMagick binaries into your project.
Optionally, set the ImageMagick version in a Heroku config like this:
heroku config:set IMAGE_MAGICK_VERSION=7.0.5-0
Make sure the version you're referencing exists on as a
.tar.xz file amon the ImageMagic releases.
(Buildpack developer note: the config setting does not show up in the compile script as an environment variable, and has to be read from a file in
$3, as explained in the Heroku buildpack docs.)
Copy the snippet above into CLI.
