[CMake] Sphinx warning.

[Andrew Maclean]

The latest version of Sphinx generates this warning when building CMake
from the master:
"WARNING: 'default' html theme has been renamed to 'classic'. Please change
your html_theme setting either to the new 'alabaster' default theme, or to
'classic' to keep using the old default."

See: https://github.com/sphinx-doc/sphinx/issues/1346#issuecomment-75538604

I'm not sure but it may be possible to import version_info from sphinx into
the  conf.py containing the version of Sphinx that is installed, and then
use that in an if statement.

Regards
   Andrew
