  First of all, if you try to build qqc2-desktop-style on a system with only Qt5 and other Tier 1 frameworks installed, you will get the following cmake configure log (https://paste.ubuntu.com/p/YRjSRWm9g6/):

    CMake Error at /home/minnehanov/prefix514/share/cmake-3.15/Modules/FeatureSummary.cmake:457 (message):
      feature_summary() Error: REQUIRED package(s) are missing, aborting CMake
      run.
  
  So, at first cmake says that KF5 is found with Kirigami as required dependency, and then next invocation of `find_package` - KF5 is NOT found, with optional deps of IconThemes and ConfigWidgets. Optional, but still not found. So, to solve that problem, change the second `find_package` invocaition to a two separate calls for individual components, not involving KF5 as whole.
