https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      sdbus-c++ is a high-level C++ D-Bus library for Linux designed to provide expressive, easy-to-use API in modern C++.
+      It adds another layer of abstraction on top of sd-bus, a nice, fresh C D-Bus implementation by systemd.
+      It's been written primarily as a replacement of dbus-c++, which currently suffers from a number of (unresolved) bugs,
+      concurrency issues and inherent design complexities and limitations.
