dnl EXTRA-LDFLAGS, EXTRA-CPPFLAGS, INCLUDES)
dnl
dnl FEATURE-NAME - feature name; library and header files are treated
dnl as feature, which we look for
dnl LIB-NAME - library name as in AC_CHECK_LIB macro
dnl LIB-FUNCTION - library symbol as in AC_CHECK_LIB macro
dnl HEADER-NAME - header file name as in AC_CHECK_HEADER
dnl ACTION-IF-FOUND - when feature is found then execute given action
dnl ACTION-IF-NOT-FOUND - when feature is not found then execute given action
dnl EXTRA-LDFLAGS - extra linker flags (-L or -l)
dnl EXTRA-CPPFLAGS - extra C preprocessor flags, i.e. -I/usr/X11R6/include
dnl INCLUDES - Any #include lines which need to be placed before the
dnl header so that it works.
dnl
dnl Based on GST_CHECK_LIBHEADER from gstreamer plugins 0.3.1.
