Build CAB file based on PREPROCESSOR value

Hi people,

I have few queries in building CAB file for smart device based on
PREPROCESSOR value.

First, Is it possible to control build based on PREPROCESSOR values in
CF. If possible then how I can do this?

Actual Scenario,

I have a application which i need to build with two different UI.
Application flow is same only difference in UI stuff (like BG, Text,
etc.). I am planning to have this as one single application, by
putting the UI images and Text under preprocessor flag. So that based
on the preprocessor value CAB file be generated.

This is the idea, is it possible to do this. kindly help,

Thanks in Advance
