REM Usage: regen_midl.cmd [Configuration]
REM   Configuration: Debug or Release (default: Debug)
REM This batch file sets the configuration parameter for the MIDL (Microsoft Interface Definition Language) regeneration process.
REM It expects one argument which represents the build configuration (e.g., Debug, Release) to be used when regenerating MIDL files.
REM The configuration is stored in the CONFIG environment variable for use in subsequent build steps.
REM Usage: regen_midl.cmd <configuration>

REM Locate the newest supported Visual Studio via vswhere.
REM The version range mirrors FwVisualStudioVersionRange in Build\FieldWorks.Toolchain.props.
REM The result goes through a temp file because cmd's for /f parsing cannot safely
