# build_windows.sh - 在 MSYS2 MINGW64 下构建 Windows 版 LogicAnalyzer
#
# 依赖（MSYS2 MINGW64 shell 中执行）:
#   pacman -S --needed --noconfirm \
#       mingw-w64-x86_64-{gcc,cmake,ninja,pkgconf,gdb} \
#       mingw-w64-x86_64-{glib2,glibmm,libusb,hidapi,libzip} \
#       mingw-w64-x86_64-{boost,qt5,python,zip}
#
# 产物: build/LogicAnalyzer-win64.zip
#
# 源码获取: libsigrok / libsigrokdecode 随仓库分发（仓库内置）。
# 若目录缺失，解析顺序: 环境变量显式指定 → 仓库内目录 → 上一级目录 →
# 自动从 GitHub clone（可用 LIBSIGROK_URL / LIBSIGROKDECODE_URL 覆盖）。
