OK, I tried changing in GNUmakefile:
ifndef LIBDIR
    LIBDIR := ${DESTDIR}/lib/*bacula*
endif

Build went ok, but installation of packages failed due some overlapping.

Error:
dpkg: error processing archive
/root/libs3-20200523/build/pkg/libs3-dev_4.1.bac_amd64.
deb (--unpack):
 trying to overwrite '/usr/lib/bacula/libs3.a', which is also in package
libs3 4.1.bac
Errors were encountered while processing:

With default build we have in packages:

However, package created with this changed lib path, some files end up
in both of them and therefore it gets rejected:

I guess changing only LIBDIR destination is not good enough.
What would be a proper way to control location for LIBS during build &
packaging process?

Does it mean Bacula Enterprise relies on the same libs3 package we are
talking about?
