Try using cpp.cxxFlags or cpp.driverFlags instead. cpp.cppFlags has a
different meaning. See
https://doc.qt.io/qbs/qml-qbsmodules-cpp.html#cppFlags-prop

This is a bug in the Conan Qbs generator which still exports compiler
options to cpp.cppFlags. See https://github.com/conan-io/conan/issues/4730

If you find the time to fix
https://github.com/conan-io/conan/blob/develop/conans/client/generators/qbs.py
that would be awesome. It's just two letters.
