In a mixing bowl, stir the softened cream cheese with the chopped dill and lemon juice until evenly combined.
Lay one tortilla flat and spread a quarter of the cream cheese mixture across the entire surface in a thin layer.
Arrange a portion of the smoked salmon slices over the cream cheese, followed by several cucumber slices and a sprinkle of capers.
Roll the tortilla tightly from one end to the other, pressing gently as you go to keep the filling in place. Repeat with the remaining tortillas and filling.
Wrap each roll in plastic wrap and place in the refrigerator for at least 30 minutes to firm up.
Remove the wraps from the refrigerator, unwrap, and slice each roll into 1-inch pieces with a sharp knife before serving.
