#  Windows 自包含打包（MinGW + Qt6 + ffmpeg）
#  用法(PowerShell):
#    ./packaging/build-win.ps1 -QtPrefix "E:\QT6.6.3\6.6.3\mingw_64" `
#        -MinGwBin "E:\QT6.6.3\Tools\mingw1120_64\bin" `
#        -Ffmpeg "C:\path\ffmpeg.exe" `
#        -DepsPrefix "C:\path\deps-prefix" `
#        -DevourerSrc "C:\path\devourer"     # 可选，离线构建用
#  产物: dist/fpv-relay-win-x64/  （含 exe + Qt + ffmpeg + 依赖，双击 run-gui.bat 即用）
#
#  前置：本机已装 libusb-1.0 / libsodium(MinGW) 到 -DepsPrefix（含 include/lib/bin），
#        且 pkg-config 可用（devourer 的 CMake 需要）。
