REM Build the native bridge DLL (wpywdlss_bridge.dll).
REM
REM Sets up the MSVC x64 environment itself, so this can be run from a plain
REM cmd or PowerShell. Requires CMake and Ninja on PATH.
REM
REM Avoids parenthesised if-blocks on purpose: the VS path contains "(x86)",
REM and expanding such a value inside a ( ) block truncates it.
