Installing openCV in to micro SD card

[ncrasta]

I am trying to install the openCV into a micro SD card. So I issued the command:

./buildOpenCV.sh -i /media/xavier/nx/opencv-lib

In the final stage, I get the following error:

CMake Error at modules/cudev/cmake_install.cmake:52 (file):
file INSTALL cannot duplicate symlink
"/home/xavier/opencv/build/lib/libopencv_cudev.so.3.4" at
"/media/xavier/nx/opencv-lib/lib/libopencv_cudev.so.3.4".
Call Stack (most recent call first):
modules/cmake_install.cmake:77 (include)
cmake_install.cmake:97 (include)

Makefile:61: recipe for target 'install' failed
make: *** [install] Error 1
There was an issue with the final installation

Can you help me to fix this issue?
Thanks
