Proximity search algorithm is only available in CBC-2.7.8. You must
install 2.7.8.

######
./configure   --enable-cbc-parallel --enable-debug -C --prefix=/usr/local

or

./configure   --enable-cbc-parallel --enable-debug -C --prefix=/home/xiwen

#####

To run,

cbc myModel - threads 8 -proximity on -solve
