In the process of uncompress, folder cannot be found

[JunCEEE]

I just found in the process of uncompress, the cpio files cannot be found.

bash: root/cpio/screen-4.1.0-0.25.20120314git3c2946.el7.x86_64.cpio: No such file or directory

I think that's resulted by the set of ROOT_D in Makefile line 43:
ROOT_D := root

Use this could solve the problem for me:
ROOT_D := $(CURDIR)/root
