I'm willing to do the work for the Windows ports, but I need more information. How is the Windows port built at Apple? Is it possible to switch it to a CMake generated project?

This was mentioned the last time you suggested switching to CMake for the Windows build: <https://lists.webkit.org/pipermail/webkit-dev/2012-April/020291.html>.

I know the last thread, so please don't hurt me if I ask dumb questions, but how does it work at the moment? ;-)
What is the root directory of a checkout? E.g. if I checkout only Source/JavaScriptCore how can I access the vsprops files from WebKitLibraries/win? Is there a checkout of this "global" files for the individual targets too? If there is a checkout of the whole tree for every target, how do you make sure that the files from the previous build are use (and not from the checkout)?
Maybe someone can explain the details a little bit more, so I can understand the requirements?

Beside this, is there a general problem with CMake for the Windows port? For the Mac port there is the problem, that CMake is not an executable provided by the system (maybe i can some time...). Since many other tools are require separate installation  on Windows anyway there should be no problem in installing CMake too?
