Currently for adding `cuDNN` libraries a module created by Stefano Sinigardi called `FindCUDNN.cmake` is used in many projects such as `Darknet`. I see the `FindCUDA.cmake` module is replaced by `FindCUDAToolkit` but still there’s no official `cmake` support for `cuDNN`. Will that be included in the near future?

The FindCUDA and FindCUDAToolkit only search for CUDA libraries that are provided as part of the CUDA SDK. Currently `cuDNN` is an additional download, and therefore would need a separte module.

The preference would be that `cuDNN` would provide a config module as part of the package, allowing existing CMake installs to work nicely.

Yes It’s optional but according to official installation notes from NVIDIA it must be copied to the same directory where the headers and libraries of `CUDA` are found so it would be nice to have `FindCUDAToolkit` take care of it IMHO.
