what about configure code? which configure macro will look for libltdl.la?

can I use
dnl use ltdl
AC_CHECK_LIB(ltdl, lt_dlopen,, [AC_MSG_ERROR([libltdl not found])])
?

the configure code looks like it does not look at libltdl.la.
is there any alternative? all macros provided by libtool seem
to depend on libltdl/ being included in the source, and we don't
want to do that.

is there any generic macro that looks for libfoo.la files and evaluates
them?

you mean the one installed as libltdl/configure? we don't want to
include a copy of libtool in each project using it.

I don't understand. we want the user of our packages to install libltdl first,
and then compile our software. so for us it is like any other library: we 
depend on it, please install it first. is there any reason that is wrong
or should not work?

sorry, your posting left me a bit confused.
