You're going about this the wrong way. All files (source and headers)
should #include all headers they make explicit use of stuff from, even
if some of them are also indirectly included.
The idea is that every file should pull in everything it needs so as
not to depend on other files doing this. There is no harm in the same
header being included multiple times provided they have #ifdef
