Dear Maintainer,

The package fails to build:

-- kmetronome 0.10.1 install prefix: /usr
CMake Warning (dev) at /usr/lib/automoc4/Automoc4Config.cmake:179 (get_directory_property):
  Policy CMP0059 is not set: Do no treat DEFINITIONS as a built-in directory
  property.  Run "cmake --help-policy CMP0059" for policy details.  Use the
  cmake_policy command to set the policy and suppress this warning.
Call Stack (most recent call first):
  /usr/lib/automoc4/Automoc4Config.cmake:243 (_add_automoc4_target)
  /usr/share/kde4/apps/cmake/modules/KDE4Macros.cmake:1026 (_automoc4_kde4_pre_target_handling)
  src/CMakeLists.txt:71 (KDE4_ADD_EXECUTABLE)
This warning is for project developers.  Use -Wno-dev to suppress it.

CMake Error at CMakeLists.txt:129 (ADD_CUSTOM_TARGET):
  add_custom_target cannot create target "uninstall" because another target
  with the same name already exists.  The existing target is a custom target
  created in source directory "/kmetronome-0.10.1".  See documentation for
  policy CMP0002 for more details.
