I comipling the opencv 4.5.5 with cuda on my orin nx get error:

_ **CMake Error: The following variables are used in this project, but they are set to NOTFOUND.** _  
_ **Please set them or make sure they are set and tested correctly in the CMake files:** _  
_**CUDA\_cufft\_LIBRARY (ADVANCED)**_  
\*\*\* linked by target “opencv\_cudev” in directory /home/hbis/Downloads/opencv-4.5.5/opencv\_contrib/modules/cudev\*\*\*

\*\*\* linked by target “opencv\_cudaarithm” in directory /home/hbis/Downloads/opencv-4.5.5/opencv\_contrib/modules/cudaarithm\*\*\*

I use jetpack 6.0, the cuda ver is 12.2, here is my cmake :

cmake   
-D WITH\_CUDA=ON   
-D CUDA\_ARCH\_BIN=“8.7”   
-D CUDA\_cufft\_LIBRARY=/usr/local/cuda-12.2/lib64

Hi,

Does OpenCV 4.9.0 work for you?  
If yes, you can find below a script to build OpenCV on JetPack 6.0:
