[Interest] Qt 5.8 failed to build on Windows: EGL/egl.h: No such file or directory

[Émeric MASCHINO]

Sorry for the late reply.

Well, I don't know what went wrong the first time.

I've uninstalled the AMD OpenGL ES SDK kit since then and ensured that
there's no EGL header/Library leftover.

Then I restarted the whole process from scratch. I had various
compilation errors when using jom (don't remember which ones) that
strangely didn't surface when using nmake. With nmake, I only had one
compilation error that disappeared when I ran nmake once again. The
process then completed as it seems (there's no global success or
failure message for the whole Qt compilation process, so it's hard to
say).

Anyway, I can use my local Qt 5.8.0-alpha build and it seems to work
with the projects I used to work with Qt 5.7. I even ran flawlessly a
new project relying upon QtVulkan module from Laszlo [1] that needs Qt
5.8.0.

So for the time being, let's say "sorry for the noise".
