Anyway, I will try to find the logs and see what I can dig up.
In the mean time I have been investigating with the source which has lead to my findings below.
So far one preliminary problem appears to be a version miss match in the /cairo-dock-plug-ins/CMakeLists.txt file which throws an error. If we fix that it builds the tools with some modules missing.
I have not tried to install from source yet because I wanted to make sure there is not a Solus solution to the problem.
This is build from source after fixing CMakeLists.txt It looks like a bunch of work ahead.
