In my experience, Visual Studio does not automatically incorporate
$BOOST_ROOT
(or $(BOOST_ROOT)/lib) into its compile and link search paths. I wouldn't
expect it to do that, either.

Could it be that you placed a current or previous value of $BOOST_ROOT into
other environment variables?  I believe that $(IncludePath) and $(LibPath)
are used by Microsoft's compile and link tools. Check the values of both.

I don't recommend that you get too comfortable with this mysteriously
"correct" build behavior. If you have multiple versions of Boost installed,
you might not be building with the version you intended. For the time
being, you could try displaying your full compile and link commands by
changing "Suppress Startup Banner" to "No" in the property pages
