My goal is to configure a build of OpenCV 4.5.1-dev with support for cuda, tesseract and QT without any cmake error..
I am getting the following error when I press the configure button on cmake gui:
CMake Error at modules/dnn/CMakeLists.txt:39 (message):

Attempt to solve the problem:
CUDA_ARCH_BIN
to what the version of the cuda
sdk (11.2). I think the flag is about the the cuda dnn versionCUDA_ARCH_PTX
to my gpu Compute capability (version) as I think it's about the Compute capability (version)
. I know what is my compute capability according to this wikipedia article

comment
on opencv issue that is like mine pointed out. After following what he said,
said I still have the error.I was receiving the same error while performing a a cmake command like this
The problem is, OpenCV is expecting WITH_CUDNN to be set to ON while it was OFF.
sudo cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D INSTALL_PYTHON_EXAMPLES=OFF \
-D INSTALL_C_EXAMPLES=OFF \
-D OPENCV_ENABLE_NONFREE=ON \
-D WITH_CUDA=ON \
-D WITH_CUDNN=OFF \ ### This is the switch I had to flip to get it working!
-D OPENCV_DNN_CUDA=ON \
-D ENABLE_FAST_MATH=1
-D CUDA_FAST_MATH=1 \
-D CUDA_ARCH_BIN=10.2 \
-D WITH_CUBLAS=1 \
-D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules \
-D HAVE_opencv_python3=ON \
-D PYTHON_EXECUTABLE=~/virtualenvs/opencv_cuda/bin/python/ \
-D BUILD_EXAMPLES=OFF ..
I was recieving the exact error as you have:
CMake Error at modules/dnn/CMakeLists.txt:39 (message):
DNN: CUDA backend requires cuDNN. Please resolve dependency or disable
OPENCV_DNN_CUDA=OFF
So Instead of -D WITH_CUDNN=OFF
I used -D WITH_CUDNN=ON
And it worked like a charm when configuring with cmake and compiling with make -j$(nproc)
