It is more complex than configure_file, although it has the advantage of
not requiring a .in file to configure. As this code is suppossed to be
understandable by people with very slim knowledge about cmake, the
simplest solution wins.

On that sense the add_custom_command was best, because when they see
"echo" and the redirection to the file they immediately guess what's
going on.
