Please suppress the annoying logo message from rc.exe

When building Qt I got hundreds of messages from rc.exe like this:

[xxx/xxx] Building RC object xxx_resource.rc.res
Microsoft (R) Windows (R) Resource Compiler Version 10.0.10011.16384
Copyright (C) Microsoft Corporation.  All rights reserved.

It can be disabled by passing the "/nologo" parameter to rc.exe. I would like contribute a patch to fix this but it's a shame that I don't know where to add this flag amount Qt's cmake scripts.
