Update CMakeLists.txt to adapte new CUDA version

[ZhuYanzhen1]

When I use a newer CUDA(Currently use 12.1), cmake .. command reports an error as:

CMake Error at cpp_to_py/gpudp/CMakeLists.txt:22 (add_library):
  Target "dp" links to target "CUDA::curand" but the target was not found.
  Perhaps a find_package() call is missing for an IMPORTED target, or an
  ALIAS target is missing?

Refer to CMake forum, Jim mentioned that find_package(CUDAToolkit REQUIRED) is obsolete. So this pr created to fit newer CUDA Toolkit. And is modified and tested on my platform:

+ Platform: Ubuntu 20.04.6 LTS on x86
+ Kernel: Linux 5.15.0-119-generic
+ Python: Python 3.11.9
+ GCC: 9.4.0
+ Pytorch: 2.3.1
+ NVIDIA Driver: 535.183.06
+ CUDA Toolkit: release 12.1, V12.1.66

Thank you for the pull request!

I think this is probably due to your newer CMake version instead of the newer CUDA version.

I tried CMake 3.17 and CUDA 12.5, and the main branch works fine.

You're right, I'm using cmake version 3.25.0 and after checkout to cmake3.17 everything is ok
