Hello,

+Yann in Cc, since there is licensing stuff involved :)

Backporting from 5.9 to 5.6 raises a red flag: Qt changed its licensing
terms between 5.6 and 5.9, and you can't backport things this way,
because Qt 5.9 is under GPLv3, while Qt 5.6 is not.

However I'm not sure about the specific status of qt5webengine. Also,
its <pkg>_LICENSE variable says:

include package/qt5/qt5webengine/chromium.inc
QT5WEBENGINE_LICENSE = GPL-2.0 or LGPL-3.0 or GPL-3.0 or GPL-3.0 with exception
QT5WEBENGINE_LICENSE_FILES = LICENSE.GPL2 LICENSE.GPL3 LICENSE.GPL3-EXCEPT \
        LICENSE.GPLv3 LICENSE.LGPL3 $(CHROMIUM_LICENSE_FILES)

which I'm not sure is correct for Qt 5.6. Indeed, many of the packages
have something like this instead:

ifeq ($(BR2_PACKAGE_QT5_VERSION_LATEST),y)
QT5MULTIMEDIA_LICENSE = GPL-2.0+ or LGPL-3.0, GPL-3.0 with exception(tools), GFDL-1.3 (docs)
QT5MULTIMEDIA_LICENSE_FILES = LICENSE.GPL2 LICENSE.GPL3 LICENSE.GPL3-EXCEPT LICENSE.LGPL3 LICENSE.FDL
else
QT5MULTIMEDIA_LICENSE = GPL-3.0 or LGPL-2.1 with exception or LGPL-3.0, GFDL-1.3 (docs)
QT5MULTIMEDIA_LICENSE_FILES = LICENSE.GPLv3 LICENSE.LGPLv21 LGPL_EXCEPTION.txt LICENSE.LGPLv3 LICENSE.FDL
endif

Could you double check the license status of qt5webengine, in Qt 5.6
and Qt 5.9 respectively ?

Thanks!

Thomas
