Okay, since you wrote that you just started with SCons and are still in 
the evaluation phase, I was unsure about how much you already know.

Thanks a lot for your clarifications, this use case scenario would 
definitely be a good example of what SCons can do, that other build 
systems can't. Now someone just has to implement it... ;)

For all my personal projects so far, I got away with a simple

   env.Program('main', Glob('*.cpp'))

. The "Glob"bing also helps for building libraries, that's how I usually 
avoid having to list each single source file.
