This macro will check for the existence of libupnp (http://upnp.sourceforge.net/). It does this by checking for the header file upnp.h and the upnp library object file. A –with-libupnp option is supported as well. The following output variables are set with AC_SUBST:
UPNP_CPPFLAGS UPNP_LDFLAGS UPNP_LIBS
You can use them like this in Makefile.am:
AM_CPPFLAGS = $(UPNP_CPPFLAGS) AM_LDFLAGS = $(UPNP_LDFLAGS) program_LDADD = $(UPNP_LIBS)
Additionally, the C preprocessor symbol HAVE_LIBUPNP will be defined with AC_DEFINE if libupnp is available.
