How to Call Flash with JLink or STLink in CMake?

[breakersun]

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?
