wondering how to set --project option for NgBuild

[yogeshgadge]

I am using it like this but get errr in ng20.1

import { Ng, NgBuild } from 'ng-programmatic';

const ngBuild: NgBuild = Ng.Build({ aot: true });

ngBuild.setArg('aot', false).setArg('baseHref', 'src/').setArg('configuration', 'dev');

console.log(ngBuild.toString());

ngBuild.run().then((result) => {});

Error: Cannot determine project for command.
This is a multi-project workspace and more than one project supports this command. Run "ng build [project]" to execute the command for a specific project or change the current working directory to a project directory.

Available projects are:

• app
• lib
• comp
