REM ============================================================
REM  geopro build helper  (Windows / MSVC + Ninja, CMake presets)
REM
REM  Usage:  build [app | all | test | run | rebuild | configure]
REM    app        (default) build target geopro_desktop (incremental)
REM    all        build all targets (incremental)
REM    test       build + run unit tests via ctest
REM    run        incremental build + launch geopro_desktop
REM    rebuild    FORCE clean rebuild (--clean-first) + launch - use when
REM               incremental seems stale / changes not showing up
REM    configure  force re-run CMake configure (after CMakeLists changes)
REM
REM  Requires: Visual Studio 2022/2026 (Desktop C++ workload, ships
REM            CMake + Ninja) and the VCPKG_ROOT environment variable.
REM  Note: cmake/ninja/cl are NOT on PATH on this machine; this script
REM        locates VS via vswhere and activates the MSVC env itself.
