#
# Win32 only
#
# This concoction mainly exists to locate the boost libraries on WIN32 in the case where our dependency/ folder has only a 
# truncated version of boost and we cannot use find_package(). The background story is that we wish to link explicitly 
# instead of using automatic linking and specifying a generic boost path to linker before each project definition.
#
# The downside of this is that it assumes the boost library names to have a particular format and only works for VC90/VC100
#
# Function: Links specified boost library defined by COMPONENT and BOOST_VERSION to PROJECT_NAME.
