This apparently causes trouble, since DBusAddons is required by e.g.
appmenu, and not found in every environment.

We stumbled upon this in Tanglu, where plasma-workspace failed to build.
Relevant buildlog excerpts:

-- Configuring done
CMake Warning (dev) at appmenu/CMakeLists.txt:24 (add_library):
  Policy CMP0028 is not set: Double colon in target name means ALIAS or
  IMPORTED target.  Run "cmake --help-policy CMP0028" for policy details.
  Use the cmake_policy command to set the policy and suppress this warning.

  Target "kded_appmenu" links to target "KF5::DBusAddons" but the target was
  not found.  Perhaps a find_package() call is missing for an IMPORTED
  target, or an ALIAS target is missing?
This warning is for project developers.  Use -Wno-dev to suppress it.

CMake Warning (dev) at plasma-windowed/CMakeLists.txt:7 (add_executable):
  Policy CMP0028 is not set: Double colon in target name means ALIAS or
  IMPORTED target.  Run "cmake --help-policy CMP0028" for policy details.
  Use the cmake_policy command to set the policy and suppress this warning.

  Target "plasmawindowed" links to target "KF5::DBusAddons" but the target
  was not found.  Perhaps a find_package() call is missing for an IMPORTED
  target, or an ALIAS target is missing?
