Problem installing opencv with cuda

edit

Hi, I have installed opencv and with cuda enabled, and all seems to compile ok. But I am getting this error which seems to be opencv related coming up when I try to compile my application-

CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108 (message): Could NOT find CUDA: Found unsuitable version "6.0", but required is exact version "5.5" (found /usr/local/cuda)

I had installed and uninstalled cuda 6 previously and installed 5.5 but am still getting this error.

Can anyone help with this?

Cheers

Steve
