ng add - please specify a project name

Inizia riproducendo il flusso di ng add @angular/material myapp in un workspace che contenga sia mylibrary sia myapp, quindi traccia il punto di ingresso del comando ng add. Il lavoro è completato quando il comando accetta il nome di un progetto e configura myapp per Angular Material invece di limitarsi a installare il pacchetto.

Repro steps

• Step 1
  starting a new project with ng new angular-project
• Step 2
  generate a library/application inside the new angular-cli project

  ng g library mylibrary
  ng g application myapp
  

• Step 3
  Add @angular/material

  ng add @angular/material myapp
  Installing packages for tooling via npm.
  Multiple projects are defined; please specify a project name
  

Observed behavior

@angular/material gets correclty installed in the node dependencies but the myapp project is not configured for using the library.

Desired behavior

The current ng add usage is: usage: ng add <collection>
Ideally this should allow passing the target app like this:

usage: ng add <collection> [options]
options:
  --project
      The name of the project.
