[Cin] with-cuda errors

[Phyllis Smith]

Stefan,
Not sure how useful the Cuda option for HW acceleration is unless you want
to use its plugins.

An authoritative statement about the Cuda HW option from the manual says:

uses Nvidia should provide the same speed-up, just without the access to
additional Cuda plugins.  Another authoritative quote from the manual.

Needless to say, I have not compiled with a later Cuda version.  I have
never been quite sure what the benefit of HV 8 cuda inclusion is.
