@CISC we can also enable boringssl in build-linux-cross.yml ?

They all probably have working libssl, so if anything, just remove -DLLAMA_OPENSSL=OFF and install libssl-dev.

That would be very surprising, they all do cross-building 👀

Why? There's cross-built dependencies. Anyway, doesn't matter, just leave them, might as well have test-cases for non-ssl build.

small note here, but we should probably move the #ifdef inside each function, as it make things easier to follow.

(this should be a follow-up PR)

This will be why my CI/CD built versions of llama-server started failing at runtime with "`https' scheme is not supported" then... :-)

For the next person scratching their head: libssl-dev is now a build dependency, without which the build won't fail but model downloads will stop working.

Thanks @timwalls.
I agree that the message provided by cpp-httplib is not helpful enough in our case.
I've opened a small PR to improve it.

docker : fix vulkan python3.13-dev and s390x build deps
e2056d1 
Two Dockerfile fixes:

1. vulkan.Dockerfile: replace apt-based python3.13/python3.13-dev
   install with uv (Astral Python manager). Ubuntu 26.04 ('resolute')
   does not ship python3.13-dev as a separate apt package, causing the
   'full' stage to fail with exit code 100 ('Unable to locate package
   python3.13-dev'). Using uv to install Python 3.13 independently of
   the system package manager resolves this.

   Also switches build-stage SSL dep from libcurl4-openssl-dev to
   libssl-dev, consistent with upstream refactor (ggml-org#18828).

2. s390x.Dockerfile: replace libcurl4-openssl-dev with libssl-dev in
   the build stage, matching upstream refactor (ggml-org#18828).

Fixes: vulkan linux/amd64 'full' stage failing with exit code 100
