./app commmand 1 command 2
should work with callbacks, but might not ever have been implemented and tested. I wrote Listing a subcommand twice should increment the count twice, in theory

./app command command
should work, though
// setup subcommands
CLI11_PARSE(…);
if(subcommand1)
cout << subcommand_x;
subcommand_x
(an option in the subcommand)
./imagetool draw 0 1 draw 1 2 draw 2 1
to make a triangle, for a related example
