Composer.json custom location

[4selin]

I have composer.json one level up from web root and did not get it working following current instructions.
https://docs.carbonfields.net/#/plugin-quickstart

specifically

"extra": {
    "installer-paths": {
        "YOUR_DESIRED_LOCATION/vendor/{$vendor}/{$name}/": ["type:wordpress-plugin"]
    }
}

It was not sufficient.

To get it working I did some tweaks:

1. I had to define base url

define('Carbon_Fields\URL', home_url('/vendor/htmlburger/carbon-fields-plugin'));

Add this to "Plugin Quickstart" please.

2. I had to manually copy build folder from

vendor/htmlburger/carbon-fields/

to

web/vendor/htmlburger/carbon-fields-plugin/

Something missing in composer install step I suppose.
