+ - Optional: CEF (Chromium Embedded Framework), for :doc:`HTML graphics <html>`.
+ If you build without CEF, the HTMLInput class will not be available from
+ the theme. You can get binary downloads of CEF from

+ http://opensource.spotify.com/cefbuilds/index.html
+
+ Simply download the right build for your platform (the “minimal” build
+ is fine) and add CEF_DIR=<path>/cef_binary_X.XXXX.XXXX.XXXXXXXX_linux64
+ on the make command line (substituting X with the real version as required).
