Cannot find the KWin version in the latest master commit

[Haraven]

Building from source code (as per instructions in the readme) fails on OpenSUSE Tumbleweed. It used to work fine, but the latest change causes an error:

> cmake ..
-- KWin Version: 
grep: /usr/include/kwineffects.h: No such file or directory
-- KWinEffect Version: 
CMake Error at CMakeLists.txt:26 (find_package):
  By not providing "FindKWinEffects.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "KWinEffects", but CMake did not find one.

  Could not find a package configuration file provided by "KWinEffects" with
  any of the following names:

    KWinEffectsConfig.cmake
    kwineffects-config.cmake

  Add the installation prefix of "KWinEffects" to CMAKE_PREFIX_PATH or set
  "KWinEffects_DIR" to a directory containing one of the above files.  If
  "KWinEffects" provides a separate development package or SDK, be sure it
  has been installed.


-- Configuring incomplete, errors occurred!

I have all of the required dependencies for Plasma 6 that were mentioned in the readme. I did check and I don't have any kwineffects.h file, in /usr/include or elsewhere. Maybe it has a different name/location under OpenSUSE?

System information:
