Vim is not multi-threaded, and it has only one command line, so you
can't run a command in the foreground of one window while editing in
another window.

I looked at ":help remote.txt" but didn't see anything there that
would do what you want, but I don't use the client-server
functionality so I could easily be wrong about that.

The easiest "solution" is to run your make command in a different
Vim instance.

Another approach is to run make in the background and send its
output to file. Then, when that make is done, you can use :cfile
command to open that file in a quickfix window.

To know when your background make is done, you can have it echo a
message to its stdout, stderr or /dev/tty, which unfortunately
messes up your display, or you can use a Unix command such as
xmessage to display a message in an X window. One nice thing about
using xmessage is that you can be working in a different workspace
from the one in which you ran make and still be informed when make
is done.
