That is, the quickfix uses the "Enter/Leave directory" printed by
make to append the right path to the detected files, so you can jump to them from the quickfix.
But it seems that it only works if
make is used as single thread, i.e.
-jN with N > 1 then the directory stack seems to be messed in my experience, and the quickfix doesn't get the right paths.
Any idea how to solve it?
