Laurent: I am glad you take care of licenses in QtWebEngine. It was in
my todo list for the last couple of month. I forgot to maintain it
through the bumps of Qt :/ and I am sorry about that.

Thomas: If I remember well, I was told to include all QtWebEngine
licenses (in v4?) and I simply run a dummy script of my own to find all
files that have some license information inside.

Then, I looked if the module was compiled and I added it into the list.
But it is hard to know in advance if the module is going to be build or
not.

Note: QtWebKit does not include the WebKit license.

Right, I was not aware about variable name clashing when I submitted the
patch.

Good catch.

This is a good idea to split file into versions.

I tested the v3 and it works fine.

But, if you do not mind, I would name the file using the Qt version
number variable $(QT5_VERSION_MAJOR).

	include package/qt5/qt5webengine/chromium-$(QT5_VERSION_MAJOR).inc

	1. We make sure to update the license file through the bumps of
	major version of Qt (5.11 to 5.12...). Otherwise, we will have
	an issue telling that the file is missing and make cannot
	include it.

	2. Qt version 5.9 and upcoming version 5.12 are also LTS which
	is confusing a bit (even if they are the latest supported in
	buildroot).
