Query: Unable to set globalVarName

I tried adding globalvarname in webpack.conf.js rules as below but build bundle is giving error in plugin webpack-stream,

Error:

[15:33:01] 'buildBundle' errored after 234 ms
[15:33:01] Error in plugin "webpack-stream"
Message:
Module not found: Error: Can't resolve '/home/hiubaid/prebidten/Prebid.js/customize/webpackLoader' in '/home/hiubaid/prebidten/Prebid.js/dist/src'

module: {
    rules: [
      {
        test: /\.js$/,
        exclude: path.resolve('./node_modules'),
        enforce: "pre",
        use: ["source-map-loader"],
      },
      {
        loader: path.resolve(__dirname, './customize/webpackLoader'),
        options: {
          globalVarName: 'myCustomGlobal'
        }
      },
      ...(() => {
        if (!isES5Mode) {

Guideline in readme.md:

Name	Type	Description	Default
globalVarName	String	Prebid global variable name	"pbjs"
defineGlobal	Boolean	If false, do not set a global variable	true
distUrlBase	String	Base URL to use for dynamically loaded modules (e.g. debugging-standalone.js)	"https://cdn.jsdelivr.net/npm/prebid.js/dist/chunks/"

For example, to set a custom global variable name:

// webpack.conf.js
module.exports = {
  module: {
    rules: [
      {
        loader: 'prebid.js/customize/webpackLoader',
        options: {
          globalVarName: 'myCustomGlobal'
        }
      },
    ]
  }
}

Even using without path gives the same error:

{
        loader: ('./customize/webpackLoader'),
        options: {
          globalVarName: 'myCustomGlobal'
        }
},

errored as
[15:49:49] 'buildBundle' errored after 160 ms
[15:49:49] Error in plugin "webpack-stream"
Message:
Module not found: Error: Can't resolve './customize/webpackLoader' in '/home/hiubaid/prebidten/Prebid.js/dist/src'

If you're building from source, you can set the global variable name by updating package.json:

Prebid.js/package.json

Line 48 in 47e5f42

"globalVarName": "pbjs",

That section of the README pertains NPM consumers, but it does make sense to make this more explicit.

Perfect, yeah I am building from the source. Thanks for the help!
