download `protobuf-all-[VERSION].tar.gz`.

This will download gmock source (which is used for C++ Protocol Buffer

**Hint on install location**
By default, the package will be installed to /usr/local. However,
on many platforms, /usr/local/lib is not part of LD_LIBRARY_PATH.
You can add it, but it may be easier to just install to /usr
instead. To do this, invoke configure as follows:

**Compiling dependent packages**
To compile a package that uses Protocol Buffers, you need to pass
various flags to your compiler and linker. As of version 2.2.0,
Protocol Buffers integrates with pkg-config to manage this. If you
have pkg-config installed, then you can invoke it to get a list of
flags like so:

pkg-config --cflags protobuf # print compiler flags
pkg-config --libs protobuf # print linker flags
pkg-config --cflags --libs protobuf # print both
For example:
For example:
c++ my_program.cc my_proto.pb.cc `pkg-config --cflags --libs protobuf`
Note that packages written prior to the 2.2.0 release of Protocol
Buffers may not yet integrate with pkg-config to get flags, and may
not pass the correct set of flags to correctly link against
libprotobuf. If the package in question uses autoconf, you can
often fix the problem by invoking its configure script like:

**Note for cross-compiling**
The makefiles normally invoke the protoc executable that they just
built in order to build tests. When cross-compiling, the protoc
executable may not be executable on the host machine. In this case,
you must build a copy of protoc for the host machine first, then use
the --with-protoc option to tell configure to use it instead. For

trying to execute the one built during the build process. You can
also use an executable that hasn't been installed. For example, if
