Hello Guys…

I am trying to properly automatizate [Get started with Firebase Crashlytics](https://firebase.google.com/docs/crashlytics/get-started?platform=ios) step **4C** and **4D**.

when it set manualy, it shall look like this:

so, what I tried is:

```auto
	set(DWARF_DSYM_FOLDER_PATH "${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}")
	set(DWARF_DSYM_FILE "${DWARF_DSYM_FOLDER_PATH}/Contents/Resources/DWARF/${PRODUCT_NAME}")
	set(INFO_PLIST "${DWARF_DSYM_FOLDER_PATH}/Contents/Info.plist")
	set(GOOGLE_SERVICE_INFO_PLIST "$(TARGET_BUILD_DIR)/$(UNLOCALIZED_RESOURCES_FOLDER_PATH)/GoogleService-Info.plist")
	set(EXECUTABLE_PATH "$(TARGET_BUILD_DIR)/$(EXECUTABLE_PATH)")
	
	add_custom_command(
		TARGET ${TARGET_NAME}
		POST_BUILD
		COMMAND /bin/sh -c "${CMAKE_CURRENT_SOURCE_DIR}/../../extralibs/firebase_ios_sdk/FirebaseCrashlytics/run"
		COMMENT "iOS: Processing and uploading dSYM files to Crashlytics"
		DEPENDS ${DWARF_DSYM_FOLDER_PATH} ${DWARF_DSYM_FILE} ${INFO_PLIST} ${GOOGLE_SERVICE_INFO_PLIST} ${EXECUTABLE_PATH}
	)

```

the link to Crashlytics/run is fine, cmake had an issue with variable “${BUILD\_DIR%/Build/\*}” but I have expected this.  
but all what it does instead is:

- from here you can see in red color all differences… some of them might not make anything bad realy, but some do (as the post\_script at the end doesnt work)

Is the another way for me to achieve automatizating the post\_script from the link I posted?

Thank you gurus!
