How do I get `make` to prompt the user for a password and store it in a Makefile variable?

Question

I\'m writing a Makefile, and some of the commands the makefile runs require a password. I\'d like to give the user the ability to either pass this in as a Makefile variable usi

To answer @joeb 's question:

$ make; echo "---Makefile---"; cat Makefile
Password: 
test
test
---Makefile---
all: first second
PASSWORD ?= $(shell read -s -p "Password: " pass; echo $$pass)
define formatted
first:
        @echo $1
second:
        @echo $1
endef

$(eval $(call formatted,$(PASSWORD)))
