Function getInstallFolderPath

getInstallFolderPath(libraryPath: string, installFolderName: string): string
Where a game with the given install folder name lives inside a location.

itch installs games directly into the location -- there is no equivalent of Steam's steamapps/common nesting -- so this is a plain join.
Parameters
- libraryPath: string
  An install location's path.
- installFolderName: string
  The game's install folder name.
Returns string
- Defined in src/locations.ts:76
