Perhaps it should be made an explicit flag,
--enable-build-Xlt, build Xlt library, against this distribution of Lesstif
--enable-build-Xbae, build Xbae library, against this distribution of Lesstif
--enable-build-Xlt-W-motif, build Xlt library, against installed *tif
--enable-build-Xbae-W-motif, build Xbae library, against installed *tif
when *-W-motif is set use the values given with --with-motif-[includes/libraries]
for making the -I's and -L's if given, otherwise specifically set the -[IL] to the
directories discovered by configure.
Yes I know some where in that configure discovery I am being naive.
