Till Toenshoff commented on MESOS-1071:
---------------------------------------

Good point, indeed. I have proposed a way to fix MESOS-550 then that should 
comply with this scheme.

> Enable building against installed third-party dependencies.

> Most of our third-party dependencies are included in the project and 
> statically linked into our resulting binaries and libraries. We would like to 
> enable building Mesos but using system installed dependencies instead.
> In certain circumstances this is more difficult because we've actually needed 
> to "patch" these libraries (either for C++11 or to alter semantics).
> Rather than eliminating our internal copies of these third-party dependencies 
> the first step should be to just enable using external (i.e., system 
> installed) dependencies. We already do this for ZooKeeper by allowing people 
> to use the --without-included-zookeeper flag during compilation. We should do 
> this for other libraries as well. In fact, for the libraries that we have not 
> patched (and even for some that we have patched) we should check to see if an 
> appropriate system installed dependency exists and preferentially use that 
> unless --with-included-dependency is explicitly used.
> Note that this issue represents a stepping stone to removing our third-party 
> dependencies from our repository.
