Part of the cmake log: -- Configuring done CMake Error at src/CMakeLists.txt:115 (add_executable): Target "akonadiconsole_bin" links to target "KF5::AkonadiXml" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing? AkonadiXml is behind tools use flag of kde-apps/akonadi
