Wildcard match on phony targets

In a GNU Makefile, if I use * in a prerequisite or $(wildcard) in an assignment it will use shell expansion to find matching files.

Is there a way to do the equivalent for phony targets? For example:

.PHONY: compile-1 compile-2
compile-all: compile-*

This is similar to this question but I don't want to have to manually list the targets as in AVAILABLE_MODELS.

"No, you have to list them" is an acceptable answer.

You don't have to quite list them. You can compute them from their differences, if that's sufficiently different:-

compiles := $(patsubst %,compile-%,1 2)

PHONY: $(compiles)

compile-all: $(compiles)

See 8.2 Functions for String Substitution and Analysis

However, if compile-N is a phony target for some compilation you ought not to have a phony target for that at all. Compilation makes real files, and they're the targets, no need for phony ones.

On the other hand, compile-all clearly should to be a phony target.
