11 dnl AC_LIB_PREFIX adds to the CPPFLAGS and LDFLAGS the flags that are needed
12 dnl to access previously installed libraries. The basic assumption is that
13 dnl a user will want packages to use other packages he previously installed
14 dnl with the same --prefix option.
15 dnl This macro is not needed if only AC_LIB_LINKFLAGS is used to locate
16 dnl libraries, but is otherwise very convenient.
