Yes, it is possible. Configure will look for dot on the path by default 
and if found, "full docs" will be enabled implicitly.

For such a simple dependency as this, basically we just need the path to 
an executable, we don't need to define actual configure arguments. You 
can simply override the value on the command line like this:

bash configure DOT=/path/to/dot
