Currently doesn't build on KDE 6, so this currently does not work on up to date systems running KDE.

Version 2.3 does build on KDE 6 if the correct flags are passed through.

I had to install extra-cmake-modules and add -DBUILD_GTK4=OFF -DBUILD_GTK3=OFF -DBUILD_XFCE=OFF to build successfully using KDE.

python is needed in makedepends.

I don't have tinyxml2 installed and it builds just fine.

Yes also needed tinyxml2 in order to build.

I had to install cmake to be able to build this. It should be added as a makedepends.
