This is a quick fix for the current situation. Proper
support will need a rewrite of part of the plugin code.
QtQuickUltralite SDK 1.x relies on environment variables
for the dependencies. SDK 2.x uses CMake variables for that purpose.
Some of the variables have been renamed, others grouped together.
Here a mapping between those is hardcoded as an urgent solution.
A proper implementation should make the plugin independent of
the existence or lack of specific environment variables. Also,
all the hardcoded information needs to be moved to the json kit
files in the SDK. Otherwise, compatibility breaks between versions
every time the built-in assumptions relating to that information change.
