@mlaurent Hi. The combination of KDE_COMPILERSETTINGS_LEVEL and KDEFrameworkCompilerSettings is not supported when requiring ECM > 5.84, things might break in lots of ways.

Please switch to using KDECompilerSettings in such cases now, which will bring all the more strict settings in a supported way now.

And looking at the CMakeLists.txt a bit more, other things which need to/ or could be twisted:

• include(KDECompilerSettings NO_POLICY_SCOPE) needs to be done before find_package(KF) etc, see also https://marc.info/?l=kde-devel&m=162893561025502&w=2
• CMAKE_CXX_STANDARD & CMAKE_CXX_STANDARD_REQUIRED already set by KDE_COMPILERSETTINGS_LEVEL == 5.85.0, see also https://api.kde.org/ecm/kde-module/KDECompilerSettings.html
