[libcamera-devel] Static linking libcamera

[Christian Rauch]

Hi Elias,

I was looking into this a while ago:
- https://patchwork.libcamera.org/patch/17901/
- https://patchwork.libcamera.org/patch/17941/

Back then, there was not really interest in statically linking libcamera
due to potential ABI incompatibility with dynamic IPA modules of
different versions. I was also hitting other issues as libcamera was
trying to resolve paths to modules via dynamic symbols in the core library.

Best,
Christian
