So you want to check the subcommands that are needed and were given and make sure all their requirements are met first. This is to get at the lower level errors with priority.

if (subc->count() > 0) {
subc->_process_requirements();
}
}
for(const auto &subc : need_subcommands_) {
if(subc->count_all() == 0) {
missing_needed = true;
missing_need = subc->get_display_name();
if (subc->count() == 0) {
try {
subc->_process_requirements();
} catch (const CLI::RequiresError&) {
throw RequiresError(get_display_name(), subc->name_);

next you are going to check the subcommands that were not parsed and give priority to missing requirements in those needed subcommands, and make the error clearer.
