I fired up my new Xavier NX (Jetpack 4.1.1) and discovered OpenCV4.1.1 was not CUDA enabled. I downloaded and built OpenCV 4.5 using the script here:
All went well, it installed, and CUDA is now enabled. However, it did not detect BLAS. I have scoured every forum and installed everything related to BLAS to no effect - the build does not detect it.
There is a suggestion that I build OpenBlas. However I see that Nvidia has an accelerated cuBLAS. So my question is: what is the best way to add BLAS to my OpenCV build? And are there any other accelerated libraries to use in place of standard libraries?
