Cmake fails on Plasma 6 Beta 2

[matinlotfali]

Running cmake for kwin-effects-cube fails with the errors below in Plasma 6 Dev 2. I am the maintainer of KDE-Rounded-Corners kwin effects and it looks like I still can't move to plasma 6. Right?

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

The cube effect is included in Plasma 6. I'll archive this repo.

[matinlotfali]

I use your repos to read and learn. That is why I tried to build it.

Now by archiving you stop me from learning how to build for plasma 6.

[zzag]

I'm not stopping you or anything.. I'm just saying that the cube effect has been upstreamed to kdeplasma-addons and there's no point to fix compilation issues here.

As for your build issue, it looks like you need to install kcmutils. But even with that sorted out, you would need to adjust to some changes in kwin, which are not described anywhere yet. Change find_package(KWinEffects) to find_package(KWin) and adjust header includes, e.g. #include <kwineffects.h> -> #include <effect/effect.h> + #include<effect/effecthandler.h>
