Errors during installation of KDE for use with Qt Creator

[panoss]

I 'm trying to install KDE in order to use it with Qt Creator.
What I've done so far (my drive letter is G):
1. I installed git in G:\Program Files\Git.
2. I installed cmake in G:\Program Files\CMake (and I put the G:\Program Files\CMake\bin in the PATH variable).
3. I cloned the repository git://anongit.kde.org/kitemmodels.git in G:/kitemmodels
4. I opened the developer console (G:\Qt\Qt5.0.2\5.0.2\msvc2010\bin\qtenv2.bat).
I run (in developer console):

set KDELIBPATH = G:\KDE
mkdir build
cd build
cmake -G "NMake Makefiles" -DCMAKE_DEBUG_POSTFIX=d -DCMAKE_INSTALL_PREFIX=%KDELIBPATH% -DCMAKE_BUILD_TYPE=DEBUG ../

Here I get the error: "CMAke error: the source directory G:/Qt/Qt5.0.2/5.0.2/msvc2010 does not appear to contain CMakeLists.txt".
What am I doing wrong?
