small cursor gnome

[rennes]

Hi,

in the GNOME environment my cursor is small, and did a link as follows 
to fix it:

mkdir -p ~/.icons/default
cd ~/.icons/default
ln -s 
/gnu/store/zr4vacpl0rlgx6m2hivr2fm2vxhgdppc-adwaita-icon-theme-3.18.0/share/icons/Adwaita/cursors 
cursors

My question is, is it necessary to create a patch-icon-theme package for 
this detail adwaita?.

Thanks
