--cxx-standard
Specify the C++ standard to use when processing the files listed in the InterfaceFiles block of the QML project file.
Description
Use this option if you want to use a newer C++ standard than the default for the interface files. Refer to the Clang documentation of the "-std" language selection command line option for the possible values: https://clang.llvm.org/docs/CommandGuide/clang.html
Keep in mind that some of the latest versions might not be supported by Qt for MCUs, as it's not necessarily using the latest version of Clang.
