Dear @dgarba,
Looks like you already filed a relavant topic at How to install cuda-toolkit on DRIVE OS 5.2.0 DRIVE AGX platform?. Could you continue the discussion on the same thread.
BTW do you need CUDA 10.2 toolkit on target to compile any package or your build just check if CUDA is present on the target using these hints? If it uses them as a hint, could you check copying those files manually to by pass build error? Because all required CUDA libs are present on target.
