In contrast do dpkg, rpm tracks which package created a directory. No
idea what happens if you remove the package which owns the directory,
but another package still owns files in there. Anyway, this behaviour
produced the following problem:
file /etc/xdg from install of awesome-[snip].x86_64 conflicts with
file from package filesystem-3.2-37.fc24.x86_64
Fix this by telling CPack to exclude these directories from the file
list.
