release CUDA program

I installed CUDA in my PC. But when I want to compile the NVIDIA SDK examples, I should type" sudo make", and it still exists an error

/usr/bin/ld: cannot find -lcutil

collect2: ld a retourné 1 code d'état d'exécution

make: *** [../../bin/linux/release/alignedTypes] Erreur 1

What should I do then?

Thanks
