Unable to build WebKit

I downloaded qt5.1 from git. And build it as:
D:\QT5.1> configure -openssl -I C:\OpenSSL-Win64\include -L C:\OpenSSL-Win64 -opengl desktop

nmake

— Success

After that I got the following error: "Unknown module(s) in QT: webkitwidgets"

And I trying to build webkit..

I install icu and add inlude and lib path to my enviroment:

SET PATH=%PATH%;D:\QT5.1\qtbase\bin
SET INCLUDE=%INCLUDE%;C:\icu\include
SET LIB=%LIB%;C:\icu\lib64

And run the build script:

perl build-webkit

And I got the following errors:
