Why on Windows the GTKMM library uses PangoFcFont? It says "invalid cast from 'PangoCairoWin32Font' to 'PangoFcFont'" and the application refuses to launch.

[UIMicro]

Hello! I am new to vcpkg and gtkmm library. Recently I want to build some cross-platform GUI application while learning a GUI framework, so I tried to install gtkmm with vcpkg on windows. However, when launching the helloworld app just compiled, I met an error "GLib-GObject-CRITICAL **: 00:42:33.816: invalid cast from 'PangoCairoWin32Font' to 'PangoFcFont'". I think it may because the compiler or code fails to select the proper font backend according to my platform. Why is that?

My compiler is MSVC. To build the project, I opened a developer powershell for visual studio, located to the project, executed cmake --preset=default and then cmake --build build. Here are my code:
