Apt's library dependencies are a lie if you look just at /usr/bin/apt,
as it relies very heavily on subprocessing for core functionality.
You'd need to check and add the dependencies of the helper binaries
that are required for apt functionality. Last I checked with 1.9.10,
it's fairly comparable.

Micro DNF is in C (using glib/gobject) today and would be in C++ in
the future. The transition from C to C++ will allow the GNOME library
ecosystem to be fully dropped as a dependency from the DNF stack. That
is substantial baggage that will finally go away.
