They have to distribute their own compiled binaries anyway since ABI
between compilers is not guaranteed :)
Since *most* GPL software is distributed over the internet, developers
using the GPLed Qt can simply point to this project somewhere in their
documentation, that would satisfy the GPL since it's the same medium
that the user got his binary ( internet )
