The root squashing is in the exports on the server side.  This maps uid 
0 to nobody,
which is why the access is denied.  One solution: make all the files 
readable by
other and the directories are readable and executable by other.  
However, since this
is generally the default it's not clear why this is happening.  You 
didn't show us
the permissions as I asked, so it's not possible to do more than 
speculate.  What does
this show (with any typos fixed)?

ls -ld / /home /home/michael.obrien /home/michael.obrien/setups 
/home/michael.obrien/setups/OpenCV 
/home/michael.obrien/setups/OpenCV/opencv-2.4.12 
/home/michael.obrien/setups/OpenCV/opencv-2.4.12/build

I'll hazard a guess that your homedir is 0700 or 0750; if so it'll need
to be 0755 (so that any user can access it, including nobody); likewise
for any other directories which you want root to read.
