I found a workaround by using a default function (like exit) to check
if libboost_graph exists. Now it works with AC_CHECK_LIB but not with
AC_SEARCH_LIBS because the exit function doesn't need any library.
Since I know this library is mandatory for the read_graphviz function,
it's OK. But I would know how to check the presence of a function
defined in a namespace, or with template parameters ?
