CMake does not scan *.o nor *.a files for dependencies. That's
GenLibDeps.pl job. As the CMake build system invokes this utility the
same way the configure&make build system does, I'm suspecting it is
something to do with the options I pass to gcc. I need to match them
with those used by make, to produce the same object and library files,
and see if this solves the problem with circular dependencies.
