Build a Makefile command by iterating in a loop

I want to "build" a command directly into my Makefile. I would need something like this:

# Makefile

CLUSTERS: 1 2 3

build:
COMMAND=""
for cluster in $(CLUSTERS) ; do \
    COMMAND+=$(shell echo "path\to\command command "$$cluster" & ") ; \
done
COMMAND+=$(shell echo "wait")
$(DOCKER_EXEC) ${COMMAND}

Then, make build would be equivalent to:

path\to\command command 1 & path\to\command command 2 & path\to\command command 3 & wait

I assume you use GNU Makefile.

In this case

CLUSTERS=1 2 3                       
COMMAND=$(subst &, &,$(addprefix path\to\command command,$(addsuffix &,${CLUSTERS}))   
COMMAND+="wait"

build:
    $(DOCKER_EXEC) ${COMMAND}
