3 dnl ACTION-IF-FOUND, ACTION-IF-NOT-FOUND,
4 dnl EXTRA-LDFLAGS, EXTRA-CPPFLAGS)
6 dnl FEATURE-NAME - feature name; library and header files are treated
7 dnl as feature, which we look for
8 dnl LIB-NAME - library name as in AC_CHECK_LIB macro
9 dnl LIB-FUNCTION - library symbol as in AC_CHECK_LIB macro
10 dnl HEADER-NAME - header file name as in AC_CHECK_HEADER
11 dnl ACTION-IF-FOUND - when feature is found then execute given action
12 dnl ACTION-IF-NOT-FOUND - when feature is not found then execute given action
13 dnl EXTRA-LDFLAGS - extra linker flags (-L or -l)
14 dnl EXTRA-CPPFLAGS - extra C preprocessor flags, i.e. -I/usr/X11R6/include
16 dnl Based on GST_CHECK_LIBHEADER from gstreamer plugins 0.3.1.
