How to Call Flash with JLink or STLink in CMake?

[breaker_]

Found the flash-st and flash-jlink target in makefile are quite handy for daily jobs.

stm32/Makefile

Lines 55 to 67 in 79d6508

 flash-st: build 
 	st-flash --reset write $(FIRMWARE) 0x08000000 
  
 $(BUILD_DIR)/jlink-script: 
 	touch $@ 
 	@echo device $(DEVICE) > $@ 
 	@echo si 1 >> $@ 
 	@echo speed 4000 >> $@ 
 	@echo loadfile $(FIRMWARE),0x08000000 >> $@ 
 	@echo -e "r\ng\nqc" >> $@ 
  
 flash-jlink: build | $(BUILD_DIR)/jlink-script 
 	JLinkExe -commanderScript $(BUILD_DIR)/jlink-script 

So I was wondering, how can we achieve the same thing in CMake process?
