[webkit-help] WebKit build failure (BackingStore.h)

[wkdev911]

Just got similar issue on the latest sync. The WebKit project failed to
build due to problems in webkit\source\webkit2\uiprocess\BackingStore.h

It has code specific for Cairo:

#if USE(CAIRO) && !PLATFORM(WIN_CAIRO)
#include <RefPtrCairo.h>
#include <WebCore/WidgetBackingStore.h>
#endif
First, it could not find the <RefPtrCairo.h> in the default include
folders. After replacing this with <WebCore/RefPtrCairo.h> (where is it
really located), this transformed to the error of not finding
WebCore/WidgetBackingStore.h: it is not present in forwarding headers. And
if you resolve this, you will get the PlatformWidget not defined error
similar to the below.
