This is the default strategy for cartesian PointLike geometries so you
don't have to pass it explicitly. It's enough to simply call, e.g.:
auto cd = bg::comparable_distance(cartesian_point,
cartesian_multi_point);
If you really want to pass it (e.g. your geometries are not cartesian
geometries but you want to calculate cartesian comparable distance),
it'd look like this:
auto cd = bg::comparable_distance(point,
multi_point,
bg::strategy::distance::pythagoras<>());
or
auto cd = bg::comparable_distance(point,
multi_point,
bg::strategy::distance::comparable::pythagoras<>());
Internally comparable strategy will be used in both cases (so the latter
one).
