In the Model class, I overrode the getTableSchema and manually defined the foreign keys like so:

public function getTableSchema()
{
$table = parent::getTableSchema();

$table->columns['sid']->isForeignKey = true;
$table->foreignKeys['sid'] = array('Click', 'm_sid');

return $table;
}

And in the corresponding table:

public function getTableSchema()
{
$table = parent::getTableSchema();

$table->columns['m_sid']->isForeignKey = true;
$table->foreignKeys['m_sid'] = array('Message', 'sid');

return $table;
}

Now the standard relation definitions work directly!

'clicks'=>array( self::HAS_MANY, 'Click', 'm_sid' ),

as well as

'message'=>array( self::BELONGS_TO, 'Message', 'sid'),
