[Development] qtwayland on i.mx6

[Keller Alexander-B42067]

The strange thing about this error is that in the config.log for qtwayland, the wayland_egl passed the config test. The config test successfully found the .pc file and grab all the necessary libraries and header files. It is strange to me that when I run make, it cannot find the EGL package.

Their is a general assumption in all qtwayland that if pkgconfig is available, then their are also .pc files for everything (e.g. wayland_egl, egl, ...)

Me personally, I've never seen a embedded GPU-driver delivering egl.pc.
Their are even Qt/qmake variables to encounter for that.

Not sure how the case for wayland-egl is (not played with it on embedded yet), but all the PKGCONFIG += ... egl ... within qtwayland look wrong to me.


Shouldn't config.test figure out what to do? ... 
 -> wayland_egl_pkgconfig tests if wayland-egl.pc is present.
 If not -> wayland_egl_direct tests if -lwayland-egl works  ....
Based on those tests their is a .qmake.cache or something like that which sets all variables so no additional "PKGCONFIG += ..." or "-l..." are needed within .pro or .pri files.



Just me 5 cents!... It could be that I haven't taken a close enough look and that I'm inherently wrong ;)
