  5. # SYNOPSIS

  6. #

  7. #   AX_LIB_UPNP([ACTION-IF-TRUE], [ACTION-IF-FALSE])

  8. #

  9. # DESCRIPTION

  10. #

  11. #   This macro will check for the existence of libupnp

  12. #   (http://upnp.sourceforge.net/). It does this by checking for the header

  13. #   file upnp.h and the upnp library object file. A --with-libupnp option is

  14. #   supported as well. The following output variables are set with AC_SUBST:

  15. #

  16. #     UPNP_CPPFLAGS

  17. #     UPNP_LDFLAGS

  18. #     UPNP_LIBS

  19. #

  20. #   You can use them like this in Makefile.am:

  21. #

  22. #     AM_CPPFLAGS = $(UPNP_CPPFLAGS)

  23. #     AM_LDFLAGS = $(UPNP_LDFLAGS)

  24. #     program_LDADD = $(UPNP_LIBS)

  25. #

  26. #   Additionally, the C preprocessor symbol HAVE_LIBUPNP will be defined

  27. #   with AC_DEFINE if libupnp is available.
