I'm confused. Pretty much the ENTIRE POINT of quickfix is capturing the output of :make (and :grep/:vimgrep I suppose, but it's called "quickfix" because it lets you quickly fix compiler errors).

If you're writing a new plugin to capture output for a particular compiler, you'll want to look at :help write-compiler-plugin

If you are using a fairly standard compiler, you should check if Vim already has a compiler plugin available. If so, you would use it (for example) like this to view the errors in a buffer without jumping immediately:

:compiler! gcc
:make!
:copen
