Need help - building 3.0 with Cuda 7.5 on Windows VS2012, static lib output

edit

If I configure CMake without CUDA (uncheck with WITH_CUDA, and uncheck all BUILD_opencv_cudaxxx modules), everything works fine. However, when I include CUDA - I have one issue in CMake, and if I continue to build, I get many errors.

The CMake error is CUDA_NVCUVENC_LIBRARY NOTFOUND - and searching for this issue it appears that NVIDIA no longer offers this library - there seems to be a bug report on this. - Don't know if this causes the problems I am experiencing wih the build.

I get a number of errors - all with a cryptic message

    The system was unable to find the specified registry key or value  - file CUSTOMBUILD

Please help - building without CUDA support is useless for my needs.

----EDIT----------

I have posted below the output from just attempting to build Opencv_core. You will notice that it listsJava, Python and Matlab as missing, none of which is in the computer, and I do not ask for any of them. Do I need to change anything in my CMake file?
