I have tried to build test project consisting of 2 libraries.
{
	"name": "project",
	"description": "An example project skeleton",
	"homepage": "http://example.org",
	"copyright": "Copyright © 2000, Your Name",
	"targetType": "library",
	"authors": [
		"Your Name"
	],
	"dependencies": {
		"project:lib1" : "~master",
		"project:lib2" : "~master"
	},
	"subPackages" : [
		{
			"name":"lib1",
			"targetPath": "lib",
			"targetType": "library",
			"sourcePaths": ["source/lib1"],
			"targetName": "app1"
		},
		{
			"name":"lib2",
			"targetPath": "lib",
			"dependencies": {"project:lib1": "~master"},
			"targetType": "library",
			"sourcePaths": ["source/lib2"],
			"targetName": "app1"
		}
	]
}
