All the VS command line does is start cmd.exe with a bat script.  The
bat script sets up various env vars, so you can probably just check
for something in os.environ(...).

But note that unless you change something, SCons does not import the
user's OS environment and pass it to the executed commands -- this is
to ensure builds are reproducible by anyone.  SCons insteads finds the
VS bat scripts and runs them itself to get the proper OS environment
to pass to cl, link.exe and so on.  This means any SConstruct should
work the same in a VS CLI or a simple cmd.exe window, so perhaps
you're asking the wrong question above.  (If you want to import the
incoming environment, of course you can do that -- see the man page.)
