I am trying to compile Vidal's 64-bit MacOSLib branch and I get a Linking Executable error from Xojo 2018r4.
Linking Executable Undefined symbols for architecture x86_64: "__NSGetThemeImage", referenced from: _MenuItemWindowMenu.HandleWindowMiniaturize%%o<MenuItemWindowMenu>o<Cocoa.NotificationObserver>o<Cocoa.NSNotification> in MenuItemWindowMenu.o ld: symbol(s) not found for architecture x86_64
