There are infinitely many ways to do this. From what I’ve seen, nearly 
every LilyPond user working on major projects ends up creating their own 
framework, ranging from elaborate systems of include files without using 
Scheme, via simpler Scheme functions, make files, programmatically 
generating files, to something like GridLy (part of OpenLilyLib) or even 
more advanced methods of simplifying maintenance at the cost of 
seriously blowing up the amount of custom program code used.
I’ve never had the time for such a large project myself, but I have the 
impression that it’s very well possible, using a well-devised hierarchy 
of files and \include-s, to do all of this with LilyPond’s native 
commands, without too much Scheme programming or external software like 
Make.
But my experience also suggests that such a system needs to be very 
thoroughly thought through (…ah, the wonders of the English language <3 
) in order to be manageable in the long run.
