WIP: Meson Port
It occured to me that the DBus build system is very complicated. Here's my proposition to replace CMake+Autotools by Meson.
Meson is way easier to handle/understand/edit that Autotools, and much linux-friendlier than CMake. (you can check the Gimp Meson port for some explanations).
Here's a WIP to port Dbus to Meson. It will be a lot of work so I'd love some feedback along the way.
