I was getting a compilation error when following the instructions.

The issue is due to the environment variable CPPUTEST_HOME not being set in the container.

The solution is to set CPPUTEST_HOME in the command to run the contaioner

docker run -it -v $MOUNT_DIR -w $WORKING_DIR -e CPPUTEST_HOME=$WORKING_DIR/cpputest gcc:7 make
