using with cloud native buildpacks?

[haliliceylan]

hi guys, how can i use this buildpack with cloud native foundation buildpacks.

I am using pack cli command like that,
pack build laravel-backend --builder heroku/buildpacks:20 -b "https://github.com/heroku/heroku-buildpack-multi"

and i added the .buildpacks

https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git
https://github.com/heroku/heroku-buildpack-php

i know maybe this issue not related directly, but i think there is someone use before.

Thx.
