[Paraview-developers] [HEADSUP] Qt5 as default

[Ben Boeckel]

Hi,

I'm going to start migrating the superbuild to do Qt5 instead of Qt4 by
default. Once this is complete, ParaView and the binaries will default
to Qt5 instead of Qt4 (though Qt4 support will still be unchanged, just
not the default).

This does mean that older Linux machines (of 2007 or so vintage due to X
and xcb being too old to get a working stack based on some prior
attempts at getting Qt5 to work on our Linux binary builder) will not be
able to run the default binaries and will require builds from source.

Thanks,

--Ben
