/* Figure out the basenames for the libdir and bindir. This
requires some explanation:
- Use opal_install_dirs.libdir and opal_install_dirs.bindir instead of -D'ing some macros
in this directory's Makefile.am because it makes all the
dependencies work out correctly. These are defined in
opal/install_dirs.h.
- After a discussion on the devel-core mailing list, the
developers decided that we should use the local directory
basenames as the basis for the prefix on the remote note.
This does not handle a few notable cases (e.g., f the
libdir/bindir is not simply a subdir under the prefix, if the
libdir/bindir basename is not the same on the remote node as
it is here in the local node, etc.), but we decided that
--prefix was meant to handle "the common case". If you need
something more complex than this, a) edit your shell startup
files to set PATH/LD_LIBRARY_PATH properly on the remove
node, or b) use some new/to-be-defined options that
explicitly allow setting the bindir/libdir on the remote
node. We decided to implement these options (e.g.,
--remote-bindir and --remote-libdir) to orterun when it
actually becomes a problem for someone (vs. a hypothetical
situation).
Hence, for now, we simply take the basename of this install's
libdir and bindir and use it to append this install's prefix
and use that on the remote node.
