To make it more clear(and to put it together) I had to do Two things mentioned above.

1- Create a file /etc/ld.so.conf.d/opencv.conf and write to it the paths of folder where your opencv libraries are stored.(Answer by Cookyt)

add /usr/local/lib to /etc/ld.so.conf.d/opencv.conf

 sudo ldconfig -v

2- Include the path of your opencv's .so files in LD_LIBRARY_PATH ()
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/opencv/lib
