Please don't do that - that option is for expert users only and is 
cunningly designed to allow you to shoot yourself in the foot ;-)

There are two possibilities here:

1) You have files with similar names to 
libboost_unit_test_framework-vc100-mt-gd-1_56.lib, but not *exactly* 
that one - and yes you really do need the file with exactly that name as 
different MSVC build options produce binary-incompatible libraries.  In 
this case, please rebuild Boost using "bjam --build-type=complete 
--with-test" to make sure you get all the possible binaries.  And yes 
this will take a while.
2) You have that file but it's not in your linker's search path - there 
should be a /LIBPATH=path-to-library-file on the linkers command line. 
If you're not using the Visual Studio IDE then you will need to check 
your IDE's documentation for help in setting that.

HTH, john.
