Description
Attached a modified image_loading example. The example is extended to use C++17 for the complete example.
While that works great for the main.cpp, it doesn't work when it is used inside a C++ class (myitem.h) and exposed to QML using qul_target_generate_interfaces.
MyItem is using std::optional a feature which got introduced in C++17.
The example cannot be compiled and fails with the following error:

It would be great if the interefacegenerator would be called with the same flags than the all other C++ files.
If that is not possible, adding an extra variable which enables the user to provide extra flags to the interfacegenerator would fix the problem.
