[oi-dev] QT5.8 alpha1 testing build

Yes I agree that you Qt4 build is the way to go for the moment.
The Qt5 builds are for the long term, I would like to get some testing
done to check if we need to fix some things and can upstream some
patches.
Maybe next year, when we are confident that Qt5 is good or if
VirtualBox breaks compatibility with Qt4 we have a fallback.

I did not prepare the oi-userland component for now as I am building
the GIT branches but the install already follows the same structure as
Qt4.8: Qt5.8 lives in /usr/lib/qt/5.8 in its own prefix.

It seems the build I obtained does not have the same issue but there
are other problems (XCB warnings and incorrect keyboard entry for some
widgets).

Yes it is perfect, no problem ;) Qt5 is just for me to prepare some
independent testing.

Rest well!
