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.
