[Development] Possible bug in qwaylandbrcmeglintegration.h when cross compiling for Raspberry Pi

[Guido Seifert]

Hi,
first I must say, I don't really know what I am doing here... new frontiers for me.

I compile Qt 5.5 (latest git master) for Raspian. Not out of the box possible, but
no rocket science either. 

The one of the problems was (is) in qtwayland. During compilation I get:

> ../../../../hardwareintegration/client/brcm-egl/qwaylandbrcmeglintegration.cpp:60:120: error: cannot convert 'QtWaylandClient::wl_registry*' to 
> 'wl_registry*' for argument '1' to 'void* wl_registry_bind(wl_registry*, uint32_t, const wl_interface*, uint32_t)'
> integration->m_waylandBrcm = static_cast<struct qt_brcm*>(wl_registry_bind(registry, id, &qt_brcm_interface, 1));

I can fix this compile error by adding 

> #include <QtWaylandClient/private/qwayland-wayland.h>

to qwaylandbrcmeglintegration.h.

Question is... is this a genuine bug, or does it only happen due to some cross compile peculiarities or a configurion glitch? 
Even if it is due to compile peculiarities, any reason not to add this header file to qwaylandbrcmeglintegration.h?
Would make it easier for others to cross compile Qt5.
