With some more aftermath done, we found this unconditional setting creates too
much trouble, so the change has been reverted now for KDECompilerSettings.
Still while at it you want to consider for now to manually add to your
project's CMakeLists.txt these lines (can be anywhere before first targets are
added):
set(CMAKE_C_EXTENSIONS OFF)
set(CMAKE_CXX_EXTENSIONS OFF)
That should ensure that your code (and any external dependencies it pulls in)
is by default more standards-compliant and portable.
Future KDECompilerSettings shall come with the option to have that set
automatically (take a peek at
https://invent.kde.org/frameworks/extra-cmake-modules/-/merge_requests/144 for
related plans)
Cheers
