Can asyncrun.vim trigger an autocommand QuickFixCmdPost to get some plugin (like errormaker) processing the content in quickfix ?

Sure you can use either g:asyncrun_exit or -post in your case without modifing any code in asyncrun.vim.

setup global callback on job finished:

let g:asyncrun_exit = "silent doautocmd QuickFixCmdPost make"

setup local callback on each command:

:AsyncRun -post=silent\ doautocmd\ QuickFixCmdPost\ make @ make
