How to add a custom made native dependency

I am looking for some documentation on how to add a native dependency. I created an example here https://github.com/BiancoA/electron-webpack-quick-start-nm and asked a https://stackoverflow.com/questions/46930628/attempting-to-link-a-native-module-using-electron-webpack stackoverflow question.

I compiled my .node module using node-gyp and now I would like to use it from electron, but I get:

```
Error: Cannot find module 'mymoduleND'

at Function.Module._resolveFilename (/Users/bianco/Src/electron-webpack-quick-start-nm/node_modules/electron/dist/Electron.app/Contents/Resources/electron.asar/common/reset-search-paths.js:35:12)

at fn (/Users/bianco/Src/electron-webpack-quick-start-nm/dist/main/main.js:65:20)
at Object.eval (webpack-internal:///./src/main/index.js:4:69)

```

some help or some documentation?
Thanks!
