Plugin code outside of your workspace

Telling VSCode about plugins, libraries etc outpside of your workspace to stop it showing errors when referencing its defines, functions etc

CTRL+SHIFT+P > Settings > Preferences: open user settings.json

Look for an existing “intelephense.environment.includePaths” entry or if not add it

	"intelephense.environment.includePaths": [
		"C:\\MyFolder\\MyLibrary1\\some_folder",
		"C:\\MyFolder\\MyLibrary2\\some_folder"
	],

Also add this to help force intellisense to look in the files

"intelephense.files.maxSize": 5000000,
"intelephense.files.exclude": [
  "**/.git/**",
  "**/node_modules/**",
  "**/vendor/**"
]
