[Buildroot] Question about adding dbus-cxx and updating libsigc

[Lang Daniel]

Hello everybody,

I would like to add dbus-cxx (https://github.com/dbus-cxx/dbus-cxx), which
compared to the existing dbus-cpp package is in active development.
The last release of dbus-cpp was in 2011.

Is having two different  dbus C++ packages preferred,
or should dbus-cpp be deprecated?

dbus-cxx depends on libsigc version 3.0.
Version 2.10.6 is currently included in buildroot.
Updating libsigc would mean updating cairomm, atkmm, glibmm and gtkmm.
Those updates bring GTK4 into the mix, which isn't a part of buildroot.
At least I couldn't find it.

I can try to provide patches to update everything and integrate
or create a separate package for libsigc3, since both versions can be
installed at the same time. Which option is preferred?

Regards,
