I was able to solve this by installing protobuf 3.x from
https://github.com/google/protobuf

P.S: Just to inform, I had to install these packages seperately to overcome
the errors in the compilation.(for Ubuntu 16.04)
    gperf (using apt-get)
    ant (using apt-get)
    default-jdk (using apt-get)
    protobuf 3.x
* There might be others which I previously installed and were used in the
compilation.
