[CMake] How to get generated dependencies

[Tom Kacvinsky]

I suppose what I could do is get the target properties for the
compiler flags (will this include compiler defines and include
directories?), add -MDD -c (using gcc, so those are the options I
want) to the compiler flags and make a custom command to generate the
file, then post process it to get the list of includes.  But the
question I have is how do I generate a list from a text file? In the
end I need a list of header files I can include in a development kit I
am creating.
