Cycles standalone: failed to create window: SDL not built with video support

Hi!
I’m building cycles standalone to be used for xml rendering with FreeCad but I receive this error:

./cycles/build/bin/cycles --samples 100 --output "./output.png"  --width 800 --height 600 "./scene.xml"
Failed to create window: SDL not built with video support

I’m on Debian testing and the compilation is fine, without errors or warnings:

./cycles  --version
3.5.0

Please can someone direct me for the solution of this problem?
I have searched extensively but have not found any other occurrences of this error.

Thank you!
Riccardo

ps. why do not export the Nurbs model to Blender?
The tessellation process often causes artifacts during render, and since I need to render a large amount of curved objects, I want to try using Cycles directly from FreeCad.
Exporting models in mesh requires retopo to achieve proper shading… ah, could Blender even just import nurbs models, even without editing tools!
