Changed message when package is not installed.

to this package is redirected to a page explaining how to install the package.

if PKG is insalled,
   <PKG>_DOCDIR is substituted to <PKG>_PREFIX/share/doc/PKG
if PKG is not installed,
   <PKG>_DOCDIR is substituted to prefix/share/hppDoc/PKG

Note: some PKG might not put their doc in share/doc/PKG.
The correct solution is to export datadir (and datarootdir) in the
pkg-config files of PKG, as well as a variable like e.g. docdir which
contain the documentation location.
