Create pattern rule for patterns in a variable?

I have this simple pattern rule

%.o : %.cpp
    recipe

I'd like to use this rule but with the added constraint that the pattern matches one of the words in a variable called FILENAMES.

Is there a way I can do this?

This is known as Static Pattern Rules.

With that syntax you provide list of possible targets, but use pattern for generate own rule for every target in this list:

FILENAMES = foo bar
# Generate list of precise targets names
FILENAMES_OBJ = $(addsuffix .o, $(FILENAMES))

$(FILENAMES_OBJ): %.o: %.cpp
    <recipe>
