Vue-cli: UMD build "window is not defined"

[randyhoulahan]

Version

3.0.0-beta.11

Reproduction link

https://github.com/vuejs/vue-cli/issues/new

Steps to reproduce

Run UMD build component in nuxt or SRR

What is expected?

We should be able to :
module.exports = {
output: {
globalObject: 'typeof self !== 'undefined' ? self : this'
}
}
"Invalid options in vue.config.js: "output" is not allowed"

What is actually happening?

"Invalid options in vue.config.js: "output" is not allowed"
related to webpack bug https://github.com/toji/gl-matrix/issues/311

vue.config.js is not a webpack config file.

Look in the repository's /docs folder to learn how to adjust webpack config in vue-cli 3

This is something we probably need to fix because with --target lib the output configurations cannot be modified.
