You *really* don't want to redefine any standard location.  Leave that 
for the user.  However, you are free to define new non-standard 
locations for you use.  For example, in my package Makefile.am I 
define 'codersdir' to be the directory path where I want some library 
modules to be installed.  Later on I define 'coders_LTLIBRARIES' to be 
the list of all the library modules (.la files) to install in that 
directory.  At install time all of these libraries get magically 
installed into the directory indicated by 'codersdir'.

You will find that Automake offers a quite flexible mechanism for 
installing in arbitrary directories.

As a golden rule, make sure that all directories used logically fall 
under the user-supplied prefix unless the user specifically says to 
install elsewhere.
