Workaround for linking to a DUB dependency instead of compiling it together with the application source code.

app-package.json

{
	"name": "myapp",
	"dependencies": {
		"mylib": "~master"
	},
	"subConfigurations": {
		"mylib": "import"
	}
}

app-source-app.d

import std.stdio;
import lib;

void main()
{
	hello();
}

lib-package.json

{
	"name": "mylib",
	"configurations": [
		{
			"name": "library",
			"targetType": "library",
			"sourcePaths": ["source/"],
			"importPaths": ["source/"]
		},
		{
			"name": "import",
			"targetType": "sourceLibrary",
			"importPaths": ["source/"],
			"sourceFiles-windows": ["mylib.lib"],
			"sourceFiles-posix": ["libmylib.a"]
		}
	]
}

lib-source-lib.d

import std.stdio;

void hello()
{
	writefln("Hello, World!");
}
