dub add-local, adds a directory as a known package that it can use as a
dependency (or to be executed).
You need to specify in the package that depends on the dependency what
dependencies you have.
I.e.
See the dependencies key:
{
"name": "myproject",
"description": "A little web service of mine.",
"authors": ["Peter Parker"],
"homepage": "http://myproject.example.com";,
"license": "GPL-2.0",
"dependencies": {
"vibe-d": "~>0.7.23"
}
}
See[0] how to specify the dependency itself.
To have different sets of dependencies/code you can use sub packages or
configurations. But I would suggest to just focus on one set for now,
while you are getting the hang of the basics.
