rem CMake configure script  (MSVC 2022 / v143, C++17, x64, NMake Makefiles)
rem
rem Usage:
rem   configure.bat ^<Debug^|Release^> [AUTO^|ON^|OFF]
rem
rem Examples:
rem   configure.bat Release OFF
rem   configure.bat Debug ON
rem
rem The build directory is derived from the configuration (see
rem config_paths.bat): build\<Debug^|Release^>\<REC_AUTO^|REC_OFF^|REC_ON^>
rem The mechanical-scanning and phase-scanning variants are merged into one
rem build; the scan mode is a runtime config item (TOML [radar_params] scan_mode).
rem
rem The 2nd argument selects the optional data-recording debug feature
rem (CMake cache variable RDP_DATA_RECORD). When it is omitted, CMake's AUTO
rem default applies: Debug = enabled, Release = disabled.
rem See docs/data_record_debug.md.
rem
rem A build directory that was configured by an older compiler (for example
rem the MSVC 2013 cache) is removed first: neither its CMake cache nor its
rem object files can be reused across a compiler upgrade.
rem
rem Encoding: keep this file ASCII-only (see msvc_env.bat).
