I realise your question is generic, but before someone else says it,
please don't configure Samba 4.10, it is long out of support ;-)

Yes, this is expected.  Bits of samba require other bits of Samba that
are not public interfaces, but are built as shared libraries to avoid
duplication of compiled code (with all the problems that creates).

The deps= lines in the wscript
