Module build_kobo 

cargo xtask build-kobo — cross-compile Cadmus for Kobo devices.

This task is a thin wrapper around cargo build --release --target arm-unknown-linux-gnueabihf -p cadmus. All dependency building (thirdparty libs, MuPDF, libwebp, mupdf_wrapper) is handled automatically by build.rs when cargo build runs.

Pre-flight steps performed before invoking cargo:

1. Verify the Linaro ARM toolchain (arm-linux-gnueabihf-gcc) is on PATH.
2. Build SQLite from source with UDL support for the ARM target (placed in target/cadmus-build-deps/arm-unknown-linux-gnueabihf/sqlite/).

Git submodules are not initialised up-front here: the Rust build script clones them lazily, only when the cached Kobo build artefacts in libs/ and target/cadmus-build-deps/... are missing. This keeps warm-cache CI runs fast by avoiding the recursive submodule clone done by actions/checkout.

The Kobo build is only available on Linux and macOS hosts.
