Better to run multiple configure/make cycles or use separate sources?

[Roman Müllenschläder <info@prodeia.de>]

Hi List!

I'm packaging a program which offers different options in using different 
compile options.

My wish is to provide different binary-packages in the end.

What should be done?
Should I prepare the 'rules' to do different compilations with 
different 'configures' and separate the files with *.install files afterwards 
or should I prepare separate sources each with it's own unique 'rules' doing 
just one compile and building only one binary each?

If the first, where can I find appropriate How-Tos?
