How to convert a quote string to a regular one in a Makefile?

I am not sure if I described the question correctly, but I am currently solving this problem as follows.

QUOTEDSTR := "hello world"
NORMALSTR := $(shell echo $(QUOTEDSTR))

Is there a more built-in way that "make" can do this without invoking the shell? Thanks

Another option:

NORMALSTR := $(patsubst "%",%,$(QUOTEDSTR))

A beta response will remove each quote in a row. The above solution will ONLY remove quotes that appear at the beginning and at the end. For instance:

QUOTEDSTR := -DTITLE=\"Title\"

A beta response will result in a value -DTITLE=\Title\when using the patsubst solution that value will not be changed.

It depends on what you want.
