OpenCV_DIR is where the source is (i.e the location of CmakeLists.txt)
OpenCV_BUILD is where the temporary / generated files will be written. (please don't use the src folder for this, else you get into trouble cleaning up)
CMAKE_INSTALL_PREFIX is the dir, where the final libs/binaries/headers will be copied
I should have mentioned that I'm using pre-built, and 2.4.6. Do I need to go into command mode to somehow to find the actual value (path) of Open_DR. I have yet to come even close to getting a config started. I found in my path, ...\Tools\Binn\;%OPENCV_BUILD%\x64\VC10\bin. The install must have put it there.

wait.
if you're using the prebuild binaries, where's the point in using cmake ?
I don't use cmake.
why bother then about cmake variables ?
As far as I know, I'm not using any cmake variables.
With a little research on Google, it appears cmake is a pretty heavy duty program. <http://www.cmake.org/cmake/help/cmake_tutorial.html> There's go to be another way to configure OpenCV.
