OpenCV 2.4.2 and trunk: cmake doesn't show CUDA options

I'm trying to compile OpenCV 2.4.2 or trunk with CUDA support on Ubuntu. On my machine, cmake does not list any of the CUDA options (such as WITH_CUDA, etc.) I'm running Lucid with a GeForce 550Ti card, driver version 302.17 and CUDA version 4.2.9. I've confirmed (using the CUDA SDK) that the gpu on my machine is up and running.

However, cmake does provide all of the CUDA options on another machine with the same graphics card, but running Ubuntu Precise, driver version 295.33 and CUDA toolkit 4.1.28.

Does OpenCV support the newest drivers and/or CUDA toolkits? Or could there be some other reason why cmake doesn't recognize CUDA on my machine?

Ah, I have CMake 2.8.0, I'll try upgrading. Is there documentation somewhere that discusses system requirements for CUDA support? I couldn't find it. Thanks!

Upgrading cmake worked, thanks!

Please accept the answer, if it is working now. We will update OpenCV docs after restarting our dev site.

Please check version of your CMake. This option is unavailable for CMake versions <= 2.8
