depending projects

[Nathaniel]

Hi autoconf folks,

I have a "politics" question about autoconf-managed projects.

Our team has developped a library (let's call it libN) and several 
applications. Each application depends on this library libN. 

The libN is being installed on very different architectures and needs sometimes 
very sensitive tuning (i.e. lots of environment variables set and options 
passed to 'configure' script, such as more libraries to link with etc). Most 
often, the applications need the same options + the libN path. What we would 
like to do is to keep the libN installation information somewhere and be able 
to get it while an application is being 'configure'd. Thus, the user gets mad 
only once, when installing libN, and then for the application he has only 
"./configure; make; make install" to type in... 

Is there a common way to do that? The easiest would to go and see config.log or 
config.status, but they are not always kept after installation...

Thanks in advance, 
            Nath.
