Right. Exactly this is a huge win in bigger projects.
Not necessarily. Even with some smaller projects (e.g. libtiff) I
usually see that the costs incurred by the recursion are greater than
the build costs. In large recursive projects, it is common for many
unnecessary things to be done after editing one source file and typing
'make', which encourages building in a subdirectory. In a
non-recursive build it is still possible to build any individual
component by specifying 'make path/to/target'. If the incantation is
too difficult to remember (or takes too much typing) then just add an
alias target name for it.
