Make doesn't automatically know that lists.o can be built by compiling
lists.hpp.  You need to add a rule for compiling lists.hpp into
lists.o.

Alternatively, rename lists.hpp into lists.cpp, since *.hpp files are
not meant to be compiled into object files.

Also, make sure you have the latest version 3.79.1 of GNU Make, as
older versions might not know about *.cpp files.
