Unable to build gegl from source

[lorange]

Hello everyone, I would like to use the AI plugins for gimp and I'm trying to install the packages (babl and gegl) and gimp from source following https://github.com/intel/openvino-ai-plugins-gimp 

Unfortunately I get to an error when building gegl. Below is the final part of the error:

Code:

Am I missing anything obvious? My laptop has an intel CPU and nvidia (quadro) GPU

Thank you very much for your help
