CMAKE build issue Windows Server: Cant find FindCUDNN.cmake CUDNNconfig.cmake CUDNN_config.cmake

[SummerPAI]

Trying to install DarkHelp on Windows Server 2019 with GeForce Ge 1660. Have installed OpenCV with DNN , Installed DarkNet as per the Darknet instructions. All Path variables have been updated ,including for CUDNN and CUDNN_PATH and server restarted. OpenCV was built from source with DNN. Darknet is running correctly from the CLI

Now trying to install DarkHelp as per the sequence in readme_windows.txt.

When running: cmake -DCMAKE_BUILD_TYPE=Release - DCMAKE_TOOLCHAIN_FILE=C:/src/vcpkg/scripts/buildsystems/vcpkg.cmake ..

using the command as above as well as when replicating via CMAKE GUI I get the following error:

CMake Error at C:/src/vcpkg/scripts/buildsystems/vcpkg.cmake:829 (_find_package): By not providing "FindCUDNN.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "CUDNN", but CMake did not find one.

Could not find a package configuration file provided by "CUDNN" with any of the following names:

CUDNNConfig.cmake
cudnn-config.cmake

Add the installation prefix of "CUDNN" to CMAKE_PREFIX_PATH or set "CUDNN_DIR" to a directory containing one of the above files. If "CUDNN" provides a separate development package or SDK, be sure it has been installed.

I located the FindCUDNN.cmake file is in several directories: Opencv/cmake darknet/share/, darknet/cmake/modules, vcpkg/ports/ Any idea how to update the configuration to point towards the correct file? Thanks in advance

Sorry, I'm not familiar with building on Windows. I have no idea how to get cmake to find CUDNN.

I'd start with a google search. Or stackoverflow, like this one: https://stackoverflow.com/questions/61533880/how-to-find-cudnn-with-cmake

Resolved by installing and running all on linux box....
