Error in installing Opencv on linux

I am trying to install Opencv in linux platform. Basically, I am following http://sysads.co.uk/2014/05/install-opencv-2-4-9-ubuntu-14-04-13-10/.

But whenever I am trying to build samples I am getting the following error-

compiling contours.c
  /usr/bin/ld: cannot find -lcufft
  /usr/bin/ld: cannot find -lnpps
  /usr/bin/ld: cannot find -lnppi
  /usr/bin/ld: cannot find -lnppc

However, I have all these files in /usr/local/cuda-7.5/. I have CUDA installed properly. the output of lspci -v -s $(lspci | grep VGA | cut -d" " -f 1)

01:00.0 VGA compatible controller: NVIDIA Corporation GK107GL [Quadro K600] (rev a1) (prog-if 00 [VGA controller])

I have solved this by editing build_all.sh which can be found in /usr/local/share/OpenCV/samples/c directory. New build_all.sh is: 

#!/bin/sh

if [ $# -gt 0 ] ; then
    base=`basename $1 .c`
    echo "compiling $base"
    gcc -ggdb -L /usr/local/cuda-7.5/lib64 `pkg-config opencv --cflags --libs` $base.c -o $base
else
    for i in *.c; do
        echo "compiling $i"
        gcc -ggdb -L /usr/local/cuda-7.5/lib64 `pkg-config --cflags opencv` -o `basename $i .c` $i `pkg-config --libs opencv`;
    done
    for i in *.cpp; do
        echo "compiling $i"
        g++ -ggdb -L /usr/local/cuda-7.5/lib64 `pkg-config --cflags opencv` -o `basename $i .cpp` $i `pkg-config --libs opencv`;
    done
fi
