did you check BUILD_opencv_python in cmake-gui as well ?
since there comes no python_d.lib with python, it can only generate a wrapper for RELEASE build
please check your release-vcproj, c++ -> preprocessor defs, if you find opencv_python_EXPORTS (at the end), replace it with CVAPI_EXPORTS, or initcv2() won't get exported
run the INSTALL project, to get the cv2.pyd copied to your python/lib/site-packages folder
