Linking error: Undefined symbols for architecture armv7

I try to move vuforia-->ImageTarget to my custome project. I switch .m filles to .mm files (AppDelegate, ViewController) becouse of the errors, but now I get this errors:

I add #import "ImageTargetsQCARutils.h" to AppDelegate. And try to run it. I also check if I import all librarys to Frameworks and the libraries are the same.
