Second error is revealed after the first one is fixed: Scanning dependencies of target qqc2desktopstyleplugin [ 40%] Building CXX object plugin/CMakeFiles/qqc2desktopstyleplugin.dir/qqc2desktopstyleplugin_autogen/mocs_compilation.cpp.o [ 60%] Building CXX object plugin/CMakeFiles/qqc2desktopstyleplugin.dir/qqc2desktopstyleplugin.cpp.o [ 80%] Building CXX object plugin/CMakeFiles/qqc2desktopstyleplugin.dir/kquickstyleitem.cpp.o /home/minnehanov/dev/kde/fw/qqc2-desktop-style/plugin/kquickstyleitem.cpp:54:10: fatal error: ksharedconfig.h: Нет такого файла или каталога #include <ksharedconfig.h> ^~~~~~~~~~~~~~~~~ compilation terminated. `plugin/kquickstyleitem.cpp` includes `ksharedconfig.h` but KConfig was not specified as a link dependency for this target. Previously it was found transitively via KF5ConfigWidgets I guess? Now without those optional dependencies it cannot be built. So KConfig should explicitly be specified as another required KF5 dependency, along with Kirigami.
