# The resulting values may be used by configure tests; thus they must not
# use, e.g., ${srcdir} or ${top_builddir}.
#
# If an installed (system) version of the library has been selected or is
# implied, then execute KPSE_LIBDIR_SYSTEM_FLAGS to set the two variables.
#
# Otherwise, set LIBDIR_INCLUDES based on the value of TL_INCLUDES and
# LIBDIR_LIBS based on the value of TL_LIBS; the optional shell code
# TL-EXTRA may modifiy these values.
# If OPTIONS specifies a Libtool library, then arrange that future configure
# test use Libtool.
# Furthermore, set LIBDIR_DEPEND and LIBDIR_RULE to values suitable as
# dependency and (multiline) Make rule to rebuild the library (assuming that
# '${top_srcdir}/../../' and '${top_builddir}/../../' point to the root of
