The question was specifically about "--xxx", note the double dash (not single dash).

Uh huh. This https://learn.microsoft.com/en-us/cpp/build/reference/compiler-options?view=msvc-170
says "You may use either a forward slash (/) or a dash (-) to specify
a compiler option."

I ran into that when looking at how to use address sanitizer with MSVC
in cmake. The instructions
said "just add -fsanitize=address", and I was all "uh, where's the
MSVC version of this?", and realized
that that *is* the MSVC version, too, since MSVC accepts dash options
as well as slash options.
