An easy way is to run your command with 'strace' to trap all the calls
to 'open':

strace make 2>&1 | grep open

That's correct. As long as you don't read these files, there's no reason
to update their latest access time. Comparing access time with modified
time is a useful way to know which files haven't been read after being
modified.
