AC_ARG_WITH() is probably the most-used solution for this, where you let
the user supply a path name as the argument, and where the option will
be documented in ./configure --help.

 [AS_HELP_STRING([--with-css-files], [location of css files
   to use with generated html])],
 [ ... set your variable to the user's provided string ... ],
 [ ... default your variable to your in-tree location ... ])

lets the end user do ./configure --with-css-files=/path/to/alternate
