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 |
|
|
|
