#   Undid above change as it turns out the value gets cached regardless of
#   an SET() command here. This was not observed in earlier tests because
#   I was ctrl-C'ing after the cmake process had past the point I was testing.

#   Added -D_LARGEFILE64_SOURCE to definitions for UNIX systems. This could
#   be a bit too global of a context in which to set it. We'll see. I also
#   added logic to set CMAKE_REQUIRED_DEFINITIONS prior to checking size
#   of off64_t. In theory, we might need to set CMAKE_REQUIRED_INCLUDES 
#   too but that was not required on the systems I tested.

#    Gunther H. Weber, Thu Jan 28 14:33:36 PST 2010
#    Added hack/workaround that ensures that the static MPI libraries get added
#    to the end of the link line. In essence, we add a dummy/empty library
#    that has the MPI libraries as dependencies. This libary is added to the
#    end of the link line of parallel executables. Doing so ensures that cmake
#    will add the depencies of this dummy library, i.e., the MPI libraries, to
#    the end of the link line.

#    Gunther H. Weber, Fri Jan 29 10:42:11 PST 2010
#    Added a new option that supports setting the rpath relative to the
#    executable location. The purpose of this is to make VisIt not depend on
#    a properly set LD_LIBRARY_PATH as some MPI variants do not pass
#    environment variables.

#    Kathleen Bonnell, Wed Feb  3 11:28:41 PST 2010
#    Encapsulated VISIT_INSTALL_x_PLUGINS into one Macro that accepts a 
#    type parameter.  Changed VISIT_THIRDPARTY_OPTION into two macros that
#    set a PATH var (for VISIT_x_DIR) or STRING var (for VISIT_x_LIBDEP).

#    Kathleen Bonnell, Tue Feb 16 14:04:16 MST 2010
#    Removed conditional setting of VISIT_RENDERING_SIZE_LIMIT, in case 
#    initial configure pass was missing something. Install our zlib on windows.

#    I corrected the rpath detection logic to handle the case were there
#    were multiple rpaths.  In particular, INSTALL_RPATH was being set as a
#    list of rpaths (the rpaths end up semi-colon separated) and I changed
#    it to a string of space separated rpaths.

    # The code creates a symbolic link from "current" to the current visit
    # version number.  Because of the coding error it succeeds when doing
    # a "make install" and fails when doing a "make package", which is
    # exactly what we want.  We do this because CPACK may create an
    # invalid tar file if the distribution contains a link to a directory.
    # This happens because CPACK removes the symbolic link and replaces all
    # the files in the directory pointed to by the symbolic link with hard
    # links.  It only stores 100 characters of path information in the hard
    # link so long paths may get truncated resulting in invalid files.  We
    # have a bunch of files with paths greater than 100 character so this
    # fails in our case.
