patsubst in GNU Makefile using variable replacements

Given the following GNU Makefile code.

ENDING = '\.cpp'
OBJ = $(SOURCES:$(ENDING)=.o) # (does not work)

This does replace nothing, however,

OBJ = $(SOURCES:.cpp=.o)

does (for cpp files). Is there a way to tell patsubst specific endings? Or at least to replace all kind of endings, like below?

OBJ = $(SOURCES:.*=.o) # (does not work)

This works:

ENDING = .cpp
OBJ = $(SOURCES:$(ENDING)=.o)

And this will replace all endings:

OBJ = $(addsuffix .o,$(basename $(SOURCES)))
