Conditional Variable Assignment

There is another assignment operator for variables, ‘?=’. This is called a conditional variable assignment operator, because it only has an effect if the variable is not yet defined. This statement: 

FOO ?= bar
-
-

is exactly equivalent to this (see The origin Function): 

ifeq ($(origin FOO), undefined)
-  FOO = bar
-endif
-
-

Note that a variable set to an empty value is still defined, so ‘?=’ will not set that variable.
