Subject: [PATCH 1/2] feat: add export support

This makes sdbus-c++ consumable from the build tree without the need for
an explicit installation. This can be very handy for e.g. testing
purposes. Crucially, downstream projects will depend on upstream to
properly export everything. Otherwise, they can't be built as static
libraries, even if sdbus-c++ is only a private dependency.

Subject: [PATCH 2/2] fix(cmake): avoid possibly empty EXPORT_SET

EXPORT_SET is empty when SDBUSCPP_INSTALL is OFF,
which leads to targets file with no targets.
