[Paraview] CUDA dependency issue when building ParaView 4.1.0-RC2 on Mac

[Utkarsh Ayachit]

Burlen,

CUDA is confusing more people than not. Also it's adding too many
variables. A cleanup to FindCUDA.cmake is certainly in the order.
Until then, I propose we swicth SQTK_CUDA variable to do a
find_package(CUDA) only if SQTK_CUDA is enabled. What do you think?
BTW, I want to tag the release soon, so we should try to keep changes
to a minimal at this point.
