Uncaught ReferenceError: vendor is not defined when using dll

As per your suggestion, I'm using dll to improve the build time but I get Uncaught ReferenceError: vendor is not defined error every time. With my experience with `Laravel Mix` I understand that I need to load the generated `vendor.js` file in dist/render-dll directoy but couldn't figure out how. I thought that this was automated and gets injected by electron-webpack.

I'm using electron-vue and my package.json looks something like this:

```json
...
"files": [
"dist/electron/**/*",
"!node_modules/deep-diff/releases{,/**/*}",
"!node_modules/bluebird/js/browser{,/**/*}",
"!node_modules/source-map-support/**/*",
"node_modules/source-map-support/source-map-support.js"
],
"electronWebpack": {
"renderer": {
"dll": [
"vue",
"vue-router",
"vuex",
"element-ui"
]
}
},
...
```

Thanks for your help.

Start with the renderer DLL configuration in package.json and inspect the generated dist/render-dll directory, especially vendor.js and the renderer entry point. Compare the packaged output with the file the renderer expects; done means the DLL build loads without the vendor ReferenceError.
