In Makefiles, $(SCRIPT) and ${SCRIPT} are equivalent, see [1]. However,
parentheses can have a special meaning w.r.t. a library's object files,
and $() is primarily associated with the shell's command substitution.
Thus, I personally prefer ${} for dereferencing macros in Makefiles
since it's quite unambiguous.
