Я не знаю библиотеки, но вы могли бы свернуть свою собственную.
После трехдневной работы с кодом я наконец-то получил гиперкарту для компиляции без предупреждений в MSVC10 и GCC (http://ideone.com/oj46o).

Обратите внимание, что это не тщательно протестировано, но оно компилируется и проходит через мой миникомплект без ошибок. (Как показано в ссылке IDEOne). Типами вершин и идентификаторами Edge могут быть любые типы, которые вы хотите, я протестировал с int
verteces и string
идентификаторами ребер.
