rem  Build Rust book_pager for Windows host and/or Android
rem  Requires: rustup + cargo
rem  Host link: MinGW at D:\tools\mingw64  (or any gcc on PATH)
rem  Android: NDK (ANDROID_NDK_HOME / ANDROID_HOME\ndk / D:\sdk\ndk)

rem  Usage:
rem    build_book_pager.bat                 host only
rem    build_book_pager.bat --android       host + android arm64 + x86_64
