> To build a module, glog, protobuf, and boost need to be unbundled so they can be used by both the module as well as Mesos.
> In a bundled build, we build the libraries into libmesos.la / libmesos.so, so every program picks them up.
> In unbundled dependencies are used, we link against all of the dynamic libraries / .so files manually. We link libmesos.so against them, then link all the other programs against libmesos.so to get the dependencies.
> This relies on the DT_NEEDED flag "copying" the .so's dependencies into the executable. [Ubuntu and Debian|https://wiki.ubuntu.com/ToolChain/CompilerFlags#A-Wl.2C--no-copy-dt-needed-entries] forcibly add the flag `-Wl,--no-copy-dt-needed-entries` to the linker to disable this.
> This breaks the build with unbundled dependencies on those platforms. Some sample error messages:
> {code}
> /usr/bin/ld: log/mesos_log-main.o: undefined reference to symbol '_ZN6google4base21CheckOpMessageBuilder7ForVar2Ev'
> /usr/bin/ld: local/mesos_local-main.o: undefined reference to symbol '_ZN6google4base21CheckOpMessageBuilder7ForVar2Ev'
> cli/mesos-mesos.o: In function `os::getenv(std::string const&, bool) [clone .part.30]':
> mesos.cpp:(.text.unlikely+0x2b): undefined reference to `google::LogMessageFatal::LogMessageFatal(char const*, int)'
> mesos.cpp:(.text.unlikely+0x33): undefined reference to `google::LogMessage::stream()'
> mesos.cpp:(.text.unlikely+0x66): undefined reference to `google::LogMessageFatal::~LogMessageFatal()'
> collect2: error: ld returned 1 exit status
> {code}
