CMake: Use FindCUDAToolkit and enable_language(CUDA) instead of FindCUDA

Fixes warning:

CMake Warning (dev) at CMakeLists.txt:696 (find_package):
  Policy CMP0146 is not set: The FindCUDA module is removed.  Run "cmake
  --help-policy CMP0146" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.
