```
CMake Warning (dev) at cmake/modules/KDevPlatformMacros.cmake:120 (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 "KDevPlatformShell" links to target "Qt5::QuickWidgets" but the
  target was not found.  Perhaps a find_package() call is missing for an
  IMPORTED target, or an ALIAS target is missing?
Call Stack (most recent call first):
  shell/CMakeLists.txt:108 (kdevplatform_add_library)
This warning is for project developers.  Use -Wno-dev to suppress it.

Comment 1 Michael Palimaka (kensington) gentoo-dev 2016-09-28 11:27:06 UTC 
This looks like a possible bogus dep upstream.

(In reply to Michael Palimaka (kensington) from comment #1)
> This looks like a possible bogus dep upstream.

No, it's simply an unconditionally required dep.
Comment 3 Michael Palimaka (kensington) gentoo-dev 2016-09-28 13:36:41 UTC 
Right, it is used for welcomepage but does not appear to have actual other usage ie. it should be linked conditionally the same way it is currently found conditionally.

But it does, the linking error happened within the shell component, not welcomepage plugin. Whilst CMakeLists.txt for the plugins dir works correctly and doesn't include welcomepage plugin dir at all, CMakeLists.txt for the shell dir requires QuickWidgets unconditionally.

Which is likely the actual bug (hence "actual" usage).
