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/): OS Kubuntu 18.04 LTS Custom-built Qt 5.14 in ~/prefix514 Other Tier 1 Frameworks also built and installed in ~/prefix514 The C compiler identification is GNU 7.4.0 The CXX compiler identification is GNU 7.4.0 Check for working C compiler: /usr/bin/cc Check for working C compiler: /usr/bin/cc -- works Detecting C compiler ABI info Detecting C compiler ABI info - done Detecting C compile features Detecting C compile features - done Check for working CXX compiler: /usr/bin/c++ Check for working CXX compiler: /usr/bin/c++ -- works Detecting CXX compiler ABI info Detecting CXX compiler ABI info - done Detecting CXX compile features Detecting CXX compile features - done Installing in the same prefix as Qt, adopting their path scheme.

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.
