The usual approach is to look for "" and assume the
next substring up to a "/" or space is the library name. This is used,
for example, by the inspect tool. I use something similar in a bash
script when I want to do a bunch of svn or other commands on a per
library basis, using grep to find the library name for each header in
boost-root/boost, and then a sed regular expression to turn the
resulting header name and library name into the command I'm after. Saves
a great deal of typing.
