This is my first Blender build, Win7-64 using cmake and MSVC 10... during configuration, cmake is giving me this error message:

"CUDA_TOOLKIT_ROOT_DIR not found or specified
Could NOT find CUDA (missing: CUDA_TOOLKIT_ROOT_DIR CUDA_NVCC_EXECUTABLE CUDA_INCLUDE_DIRS CUDA_CUDART_LIBRARY)
CUDA compiler not found"

Is this a component missing from the blender trunk? or is it an external component missing from windows?

...and of course how do i go about fixing this?

...and 5 minutes later i figured out the problem. In case anyone else has the same question, check out this link:
