Fix cuda11 * use cudnn_version.h to detect version when it is available * remove nppi from CUDA11 * use ocv_list_filterout * dnn(cuda): temporary disable CUDNN 8.0

FindCUDNN
|
|
---------
|
|
|
|
Finds the cuDNN library.
|
|
|
|
Requires:
|
|
^^^^^^^^^
|
|
|
|
find_cuda_helper_libs from FindCUDA.cmake
|
|
i.e. CUDA module should be found using FindCUDA.cmake before attempting to find cuDNN
|
|
|
|
Result Variables
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
This will define the following variables:
|
|
|
|
``CUDNN_FOUND``
|
|
``CUDNN_INCLUDE_DIRS`` location of cudnn.h
|
|
``CUDNN_LIBRARIES`` location of cudnn library
|
|
|
|
Cache Variables
|
|
^^^^^^^^^^^^^^^
|
|
|
|
The following cache variables will be set if cuDNN was found. They may also be set on failure.
|
|
|
|
``CUDNN_LIBRARY``
|
|
``CUDNN_INCLUDE_DIR``
|
|
``CUDNN_VERSION``
|
|
|
|
``CUDNN_VERSION_MAJOR`` INTERNAL
|
|
``CUDNN_VERSION_MINOR`` INTERNAL
|
|
``CUDNN_VERSION_PATCH`` INTERNAL
|
|
|
|
