phony for targets with variable name using percent sign

I have a makefile that is using %.target. I am wondering how I could add those to .PHONY.

Simplified, this might look like this.

%.build:
    docker build -t $* .

It’s not exactly clear what you want to do but if what you want is for any command line goal that matches the pattern %.build to be treated as phony you can add this to your makefile:

.PHONY: $(filter %.build,$(MAKECMDGOALS))
