dnl @synopsis AX_BOOST_THREAD

dnl
|
|
dnl This macro checks to see if the Boost.Thread library is installed.
|
|
dnl It also attempts to guess the currect library name using several
|
|
dnl attempts. It tries to build the library name using a user supplied
|
|
dnl name or suffix and then just the raw library.
|
|
dnl
|
|
dnl If the library is found, HAVE_BOOST_THREAD is defined and
|
|
dnl BOOST_THREAD_LIB is set to the name of the library.
|
|
dnl
|
|
dnl This macro calls AC_SUBST(BOOST_THREAD_LIB).
