So, on linux/unix systems lib goes in front of the library so that it 
can be used with -l.  For example libfoo.a or libfoo.so can be linked 
with -lfoo.  However on windows there is no implied prefix with linking, 
to link library foo you put foo.lib on the link line.  That will link to 
foo.lib which might be a static library or an import library for 
foo.dll.   So, by adding lib to foo.lib on windows libfoo.lib, you have 
changed the name of the library from foo to libfoo.
