fix: Create destination directory if it does not exist.

1. Why is this change neccesary?
Because the destination directory may not exist on the users machine.

2. How does it address the issue?
By implementing an order-only prerequisite to the copy recipe that creates the
destination directory if it does not exist.

3. What side effects does this change have?
None!
