Yes, the makefile should only output ANSI color codes when it is
actually writing to the terminal. You would need to tell vim to strip
aways those ansi escape codes.

A quick google search, reveals how you can get rid of those chars:
https://unix.stackexchange.com/questions/4527

So something like this perhaps:

set makeprg=make\ \\\|\ sed\ -r\ "s/\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[m|K]//g"

Okay, quoting might become very ugly. You might want to create a
wrapperscript like this:

#!/bin/sh
make | sed -r "s/\x1B\[([0-9]{1,2}(;[0-9]{1,2})?)?[m|K]//g"

and use this for make like :set makeprg=my_make

However, I would still open a ticket at that repository and ask if there
is a way to build without outputting ansi escape codes

Best,
Christian
