gnu make: list the values of all variables (or “macros”) in a particular run

Question

How can I list the current value of all variables (also called macros) in a Makefile when running make?

E.g. if this is in the Makefile:

CUR-DIR := $

Thanks to @kevinf for the great idea. I would suggest a minor change to prevent .VARIABLE itself from printing out in the variable list:

$(foreach v, $(filter-out .VARIABLES,$(.VARIABLES)), $(info $(v) = $($(v))))
