RC3: Building Sikuli from Source Tesseract OpenCV Errors --- no longer supported

I am trying to build Sikuli on 64bit windows from the source code. I have all the prereqs downloaded and installed. Following the directions in build-win32 I run:

cmake -G "NMake Makefiles" -D CMAKE_BUILD_TYPE=Release ..

in sikuli\sikuli-script\build\ directory.

I get the following errors even though I have set both TESSERACT_DATA_DIR and OpenCV_DIR environment vars

C:\git\sikuli\sikuli-script\build>cmake -G "NMake Makefiles" -D CMAKE_BUILD_TYPE=Release ..
Tesseract-OCR Data Path: TESSERACT_DATA_DIR-NOTFOUND
Tesseract-OCR Data Path: TESSERACT_DATA_DIR-NOTFOUND

See also "C:/git/sikuli/sikuli-script/build/CMakeFiles/CMakeOutput.log".

OpenCV_DIR is set to C:\Program Files\opencv\build
TESSERACT_DATA_DIR is set to C:\git\tesseract-2.00.eng\tessdata

What am I doing incorrectly?

Thanks
