Sounds like a problem with your OpenCV installation. If you're still having this issue, please let me know what OS and compiler you are using, thanks.

/usr/bin/ld: cannot find -lcufft
/usr/bin/ld: cannot find -lnpps
/usr/bin/ld: cannot find -lnppi
/usr/bin/ld: cannot find -lnppc
/usr/bin/ld: cannot find -lcudart
