En el makefile del workspace me pone esto:
.PHONY: clean All

All:
   @echo "----------Building project:[ ModHerramientas - Debug ]----------"
   @cd "ModHerramientas" && "$(MAKE)" -f "ModHerramientas.mk"
clean:
   @echo "----------Cleaning project:[ ModHerramientas - Debug ]----------"
   @cd "ModHerramientas" && "$(MAKE)" -f "ModHerramientas.mk" clean
Y este es el mk de herramientas project:
