[Buildroot] [PATCH v5 06/13] package/opencv: add qt5 support

[Yann E. MORIN <yann.morin.1998@free.fr>]

Samuel, All,

On 2015-06-07 12:26 +0200, Samuel Martin spake thusly:
> Starting with the 2.4.6 release, OpenCV supports both Qt4 and Qt5,
> but only one can be enabled at the same time.
> 
> Since Buildroot does not support Qt4/Qt5 co-existence, we keep the Qt
> support knob as a boolean, but make it depend on BR2_PACKAGE_QT or
> BR2_PACKAGE_QT5, and automatically uses the enabled one.
> 
> Note that we usually use 'select ...' to express the dependencies
> between packages, but in this case, we cannot since the Qt4/Qt5
> co-existence exclusion is not handled by a simple choice, but by a
> dependency. This makes impossible using 'select ...' for the Qt
> support knob without triggering a circular dependency at the kconfig
> level.
> 
> Besides, we already use 'depends on ...' to express the dependencies
> with some "big" packages (like xorg or libgtk2). qt or qt5* packages
> are fairly big. So, I don't think it will hurt that much to use a
> 'depends on ...' statement in this case.

We no longer support avr32. I should know, I ditched it! ;-)

Otherwise, looks good.
