| # Thin wrapper: derive version + release flag + matrix (engine-meta, from CMakePresets | |
| # vendor.anira), then hand off to the shared _build-backend.yml pipeline. CPU SHARED only; | |
| # per target we either repackage an upstream download.pytorch.org prebuilt or build from | |
| # source where PyTorch ships none. Consumed via find_package(Torch), so archives preserve | |
| # the full package tree (include/ lib/ share/ [bin/]). | |
| # | |
| # Triggers: | |
| # - push/PR touching libtorch sources or shared CI -> validate only (no release) | |
| # - tag v<anira-version> (e.g. v2.0.3) -> build at its VERSION, publish to that release | |
