Thanks Reto, Jonni,
I am still puzzled (please see harbour comments below).
I assume that the XDG naming is only to be used in the program code 
itself (not in .pro or .yaml).
So, I would need to replace (in .pro)

data.files = checklistsdata/*
data.path = /home/nemo/Documents/checklistsdata


data.files = checklistsdata/*
data.path = /usr/share/$NAME/checklistsdata

and in first execution copy /usr/share/$NAME/checklistsdata to 
$XDG_CONFIG_HOME/$NAME/checklistsdata or 
(though I would think that $XDG_DATA_HOME would be better)
The problem is that (certainly in my next app with loads of map data) 
data files end up in /usr/share/$NAME.
There is no way for the app (no root permission) to clean up the 
/usr/share/$NAME directory.

Comments from harbour:
We do not allow to install files into /home/nemo from rpm. The user or 
the path for the home dir or the user under which the app runs could 
change in future! (btw that does not mean we have currently plans to do 

Please create the folder with parents during run time if it does not 
exist (following the XDG Base Directory Specification [0]). If files are 
needed, install them under /usr/share/$NAME and copy them during run 
time to $XDG_CONFIG_HOME/$NAME folder.
