openLilyLib's oll-core has the tool \includePattern that can be used 
directly for your cause. See 
https://github.com/openlilylib/oll-core/blob/master/util/usage/include-pattern.ly 
for an example file and 
https://github.com/openlilylib/oll-core/blob/master/util/include-pattern.ily 
for the implementation. What you really need (i.e. the function you 
might tweak into your own set-up) is the for-each starting on line 79.
