Download of cmake fails, because the file doesn't exists / the URL is wrong.
I verified this with the branches "master" and "kde-4.12".

The default target in
%kderoot%/emerge/portage/dev-util/cmake/cmake-2.8.4.2011622.py
is "2.8.12.1". The (non existing) URL is:
http://www.cmake.org/files/v2.8/cmake-2.8.12.1-win32-x86.zip

I fixed this by switching to 2.8.12, but i'm not sure if that's works (cmake is found, but I can't build KDE because of another, unrelated issue).
URL: http://www.cmake.org/files/v2.8/cmake-2.8.12-win32-x86.zip
