[Fedora-packaging] Unpackaged optional dependencies

We had a similar issue for the packaging of SOCI (
http://soci.sourceforge.net,
https://admin.fedoraproject.org/pkgdb/acls/name/soci), which is an
abstraction layer on top of third-party database back-ends/libraries,
including some not well supported by Fedora or even proprietary (Oracle).
So, we used "%bcond_with oracle" rules, translating into "--with/--without
oracle" options on the rpmbuild command-line. You can have a look at the
RPM specification file:
http://pkgs.fedoraproject.org/gitweb/?p=soci.git;a=blob_plain;f=soci.spec;hb=HEADfor
more details. In other terms, while mainstream Fedora does not provide
the Oracle sub-package, anyone can easily build the RPM if he/she has all
the necessary software stack and rights to use on his/her environment.

Hope it helps.

Kind regards

Denis
