Public dependencies are the dependencies that any user of a particular
system will also need. Private ones are dependencies that are
For example, ldb uses tdb internally but anybody using tdb
doesn't need to include any tdb headers, so tdb is a private
ldb also uses talloc and talloc is required by users of ldb, so ldb is
a public dependency.
That's the intended situation, the settings for most subsystems isn't
correct yet. A lot more subsystems have public dependencies where they
can be private, for example.

What do you mean exactly? External libraries found by configure should
be defined using SMB_EXT_LIB(), or do you mean something else?
