This is my own testing version of cassiapp, I have no idea if I'll ever get the stuff to work. But if you want to use this anyway, just follow the instructions
prefix.tar.gz
from cassiaext inside the build
folderprefix
folder that is inside build
to tar.gz
After, that, just import them to Canela.
For some reason, WINE doesn't want to create the damn prefix. You can try to start your own prefix using a WINE from Termux like what I did, however, I haven't got anything to output to Termux:X11 (although I manually tested something like xclock and it worked)
