Hi Thiago,
should i just take your word or do you also have a link for this?
the requirement to document this is also more than qt company tells commercial
customers. they they if you use modules which are under commrcial license
as qtcore pretends to be, you can be silent about anything used in there.
and while i am at it, there is also

Ps.: And then there is also the modified freetype code in qtgui’s raster code
