I already have the source files split up into their myriad sub-projects, 
all I really want is to tap into the dependency generator to get a list 
of header files pertinent to any given project.

In particular, this is useful for performing search operations.

Remember: Visual Studio allows you to constrain multi-file searches a 
number of ways, one of which is "Just this project".

When you have thousands of header files, having every header in your 
codebase arbitrarily crammed into your project file means that every 
project-only search is going to return too many results.
