dnl AC_LIB_PREFIX adds to the CPPFLAGS and LDFLAGS the flags that are needed
31
dnl to access previously installed libraries. The basic assumption is that

dnl a user will want packages to use other packages he previously installed
33
dnl with the same --prefix option.
34
dnl This macro is not needed if only AC_LIB_LINKFLAGS is used to locate

dnl libraries, but is otherwise very convenient.
