Please help me with this linker issue:

I'm now trying to use arsd.mssql.

And the linker requires the following libs:

libcmt.lib
libvcruntime.lib
libucrt.lib

When I copy those files (I know it's bad.) It gives the error:
BuildSys: Link Error: 1 lld-link: error: undefined symbol: fileno

This is something triggered by a bad odbc32.lib or what?

I've found libcmt.lib in a VS2022 folder that SQL Management 
Studio installed for itself just today.

I also have 2 Deprecation messages:

Deprecation: module `etc.c.odbc.sql` is deprecated - The ODBC 3.5 
modules are deprecated. Please use the ODBC4 modules in the 
`etc.c.odbc` package.

3.5 modules are deprecated. Please use the ODBC4 modules in the 
`etc.c.odbc` package.

I tried to use etc.c.odbc.odbc64 then. It had some parameter type 
mismatches: cast(short) from int. And then I got the same 
frustrating libcmt.lib linker error. o.O
