make error:/usr/bin/ld: warning: libcudart.so.8.0, needed by /usr/local/opencv-3.2/lib/libopencv_core.so, not found (try using -rpath or -rpath-link)

[HeyMrYu]

hello,
When I enter " make -j 16 USE_CUDA_PATH=/usr/local/cuda", but I got some error.

/usr/bin/ld: warning: libcudart.so.8.0, needed by /usr/local/opencv-3.2/lib/libopencv_core.so, not found (try using -rpath or -rpath-link)
but I can find libopencv_core.so in /usr/local/opencv-3.2/lib

Can you explain why I got this error? Thank you very much.
