You already have it -- this functionality is built into the preprocessor.
Given foo.cc, you can get the dependencies for foo.cc output when compiling
it, using

gcc -MMD foo.cc -o foo.o

The dependencies for foo.cc will end up in a file named foo.d.

The dependencies for your whole project should be: your exe depends on all
the .cc files and on any libraries that compile as part of the project; and
each of the .cc files depends on the dependencies in the corresponding .d
file. Any of the libraries compiled in the project depend on any other
libraries they use and on its .cc files, etc.

The dependency information will be based on #include "foo.h" directives but
excluding #include <foosystem> directives including standard system headers.
It works the same for plain .c files as for C++ files.
