rem ===========================================================================
rem Shared MSVC 2022 (v143) environment setup.
rem
rem Called by configure.bat / build.bat / clean.bat. It:
rem   1) locates the MSVC 2022 toolset and cl.exe (default Hostx64\x64);
rem   2) calls vcvarsall.bat to set PATH / INCLUDE / LIB (nmake comes with it).
rem
rem NOTE: this script does NOT use setlocal, so the variables it defines stay
rem       in the caller's environment (all callers run under setlocal).
rem
rem Override the defaults with these environment variables:
rem   VS2022_DIR            Visual Studio 2022 install root
rem   MSVC_TOOLSET_VERSION  MSVC toolset version
rem   MSVC_HOST_ARCH        compiler host architecture (x64 / x86)
rem   MSVC_TARGET_ARCH      target architecture (x64 / x86)
rem
rem Exit code: 0 = ok, non-zero = setup failed (caller must abort).
rem
rem Encoding: keep this file ASCII-only (cmd.exe parses .bat in the OEM code
rem           page, UTF-8 comments would break parsing on non-UTF-8 consoles).
