Check Paul's site

and page:

I'm using the mechanism described there and it's working nicely. I did have
to write a separate script/batch-file to parse the preprocessor output (to
retrieve the included header files) because our compiler does not support an
option to generate dependency information. If you're using *nix you probably
already have the tools you need; when you're using *dows you might want to
have a look at tools like Cygwin, GNUWin32 and MinGW to do the trick. Check
your compiler options for more info.

Good luck!
