[CMake] Cuda7 issues

[James Bigler]

FindCUDA doesn't look for a specific version, but rather checks to see if
the version it found is the one you asked for.  You can set the
CUDA_TOOLKIT_ROOT_DIR to the one you want (and reconfigure - I've set it up
to easily change this), or you can change your environment in Windows to
point to the default version of CUDA you want (CUDA_PATH).

It would be nice if it could search about and find an appropriate version.
