ax_boost_python

This macro checks to see if the Boost.Python library is installed. It also attempts to guess the currect library name using several attempts. It tries to build the library name using a user supplied name or suffix and then just the raw library.

If the library is found, HAVE_BOOST_PYTHON is defined and BOOST_PYTHON_LIB is set to the name of the library.

This macro calls AC_SUBST(BOOST_PYTHON_LIB).

In order to ensure that the Python headers are specified on the include path, this macro requires AX_PYTHON to be called.
