Using edeliver in a git monorepo

Hey,

I would like to know if there is a config variable to indicate the Mix execution path.

I am working with a git mono repo organised like below:
core/
+engine
+worker
+cli
+website

I would like to indicate edeliver to build the release in the engine directory.

when I launch mix edeliver build release it tries to build in the root directory.

Is-anyone have a suggestion ?
