Start by reproducing the Windows example build and inspect windows/CMakeLists.txt alongside win_toast_plugin.cpp and DesktopNotificationManagerCompat.cpp. Trace the missing WINRT_* symbols and compare the plugin's link configuration with the failing linker output. Done means the win_toast example builds successfully without unresolved external symbols.
