# 在 Ubuntu 24.04.x（x86_64 宿主机）上为多个 Tauri 2 + Vue 项目打出 amd64 与 arm64 的 .deb。
#
# 依赖（示例，按 Tauri Linux 文档补齐）：
#   - Node/npm、Rust、@tauri-apps/cli
#   - rustup target add aarch64-unknown-linux-gnu
#   - 本机 amd64 与交叉 arm64 的 libwebkit2gtk、gtk 等 -dev 包及 pkg-config 布局
#
# 用法：
#   ./scripts/build-linux-deb-all.sh              # 构建 PROJECTS 中全部项目
#   ./scripts/build-linux-deb-all.sh call-client  # 仅构建指定项目（可多个）
