In the platform configuration wizard, there should be an entry for BlackBerry, and it should contain an expandable "Advanced Settings" section where user could set a path for the root BlackBerry NDK location. It will be filled initially by a default path, e.g. ~/BlackBerry. The text next to the platform checkbox should say "Not Configured" by default. This ticket just covers the UI aspect. There will be separate tickets for dealing with the actual configuration once "Configure" is clicked as well as auto-detecting if BlackBerry is already installed in the default location to update the UI state accordingly.
