You can write a subclass of PPCallbacks and attach an object of that subclass to the preprocessor. Then, you'll see whenever we #include a file, #define a macro, etc.

Alternatively, you could extend the (optionally-built) PreprocessingRecord to specifically track #includes (it already tracks macro definitions) and use that information.
