There has been some other discussion around here about libtorrent not 
building with VC7 anyway, but to answer your question:

That library (with that name) is built by the bjam build system when you 
build/install Boost, please refer to the getting started guide at 
http://www.boost.org/more/getting_started.html for more information.

If you really want to go it alone, then defining BOOST_ALL_NO_LIB when 
building will disable the auto-linking feature (again this is in the getting 
started guide).

The reason for this feature BTW is to ensure that the library you link 
against is binary compatible with your current build settings: since there 
are 6 binary-incompatible build options for VC7 at least, picking the right 
variant otherwise is error prone.
