eeze.pc is fine, and eeze gets detected by pkgconfig and the
-L{library_path} is present. The problem is to enable eeze mounting
there is a check in configure.ac to test the presence of
eeze_disk_function using AC_CHECK_LIB (see line 397-411 in
configure.ac). The way I understand from just reading up on autoconf.
AC_CHECK_LIB only uses the default library paths, and there is nothing
to include the additional paths in the test and unfortunately I don't
know how to put them there either.
