Add missing global definition
// NOTE: imgui_user_config.h is included by imgui.h which is included with precompiled header, so no need to include it here once more
+// global definition "Enable ImGui Assertions"
+bool g_ImGuiAssertionsEnabled{ true };
+
#ifdef NDEBUG
// inline _wassert decl for NDEBUG as it is not emitted inside assert.h header in this case
extern "C" _ACRTIMP void __cdecl _wassert(wchar_t const* _Message, wchar_t const* _File, unsigned _Line);
