I'd do this in Python, right in your SConstruct/SConscript file.

Create a list of all "main_*.cpp" files, scan each one of them with a 
simple regex for include statements and then compile the list of sources 
from that.

Trying to map this process to SCons structures will probably not give 
you the desired result. Just put the nice feature of SConstructs being 
actual Python scripts to good use here...

Best regards,
