Pointer Events are currently defined as follows:
ENABLE_POINTER_EVENTS = $(ENABLE_POINTER_EVENTS_$(WK_PLATFORM_NAME));
ENABLE_POINTER_EVENTS_iosmac = ENABLE_POINTER_EVENTS;
ENABLE_POINTER_EVENTS_iphoneos = ENABLE_POINTER_EVENTS;
ENABLE_POINTER_EVENTS_iphonesimulator = ENABLE_POINTER_EVENTS;
ENABLE_POINTER_EVENTS_macosx = ENABLE_POINTER_EVENTS;
This excludes watchOS but there's no good reason why that platform should be excluded.
