MESOS-3843 will help us understand what we need in order to make this a reality. Once we figure out what the dependencies are on a running slave binary, we can proceed. At a minimum we will need to:
1. Add a `CMakeLists.txt` file to `src/slave/`.
2. Add an executable that compiles `src/slave/main.cpp` against all the slaves dependencies (i.e., with relevant `link_directories` and `include_directories` passed in). For an example of how to do things, have a look at `src/CMakeLists.txt`. We shouldn't need to add any extra configuration logic, unless we've missed a dependency of the slave.
