Multiple configure.in files with libtool

[Tod W. Milam]

Hello -

I'm not sure if this is an autoconf or libtool problem, but libtool is
giving me the error so I'm starting with this list.

I have a project that uses plugins (Libtool modules) for changing the
destination of the output.  I have everything working fine using one
top-level configure.in file.
Each plugin depends on different third-party libraries and only gets
compiled when that library is found on the system.
Using one top-level configure.in seems to link all found libraries with
all other parts of the project.  Therefore I am trying to put
configure.in files in each of the plugin directories so that the
third-party libraries will only be linked to the appropriate module
file.
The configure part seems to work fine and everything compiles and
installs fine, but when I try to use one of the newly created modules I
get "file not found" returned from the failed call to lt_dlopenext.

Here is the top-level configure.in:

I am using the following versions of autotools:
autoconf (GNU Autoconf) 2.50
automake (GNU automake) 1.4-p4
ltmain.sh (GNU libtool) 1.4 (1.920 2001/04/24 23:26:18)

Any ideas or maybe a pointer to an example?

Thanks,
Tod Milam
