How to pack Sdk project's dependencies into generated nuget package?

I have a Sdk project which depends on several nuget projects, and I use below sections to control how the project is packed:

```xml

True

True
Sdk\


```

After packing the nuget package will look like below:

```
(root)
| - Sdk
| | - Sdk.targets
| | - Sdk.props
| - tools
| - ProjectAssembly.dll
```

And I referenced some tasks from ProjectAssembly.dll in Sdk.targets:

```xml

```

However, the built assembly needs its dependent assemblies, which was not restored when I use the sdk in project. Is there any way to pack these dependencies into the package, or will msbuild restore them for me in future?
