Compile ZeroMQ as static library

On some environment can be useful to have ZeroMq as static library rather than a dynamic one.
In order to create a static ZeroMQ library, follow these steps.

To do so, under ubuntu :

1. sudo apt-get install build-essential
2. sudo apt-get install libtool
3. sudo apt-get install automake
4. sudo apt-get install autoconf
5. sudo apt-get install uuid-dev
6. Download the tarball for the libsodium from the Libsodium website
7. Extract the tarball in a directory
8. go in the directory
9. ./configure --enable-static --disable-shared
10. make
11. sudo make install
12. Download the tarball from the ZeroMQ website
13. extract the tarball in a directory
14. go in the directory
15. ./configure --enable-static --disable-shared
16. make
17. sudo make install

At this point is better to close all the terminals and re-open them.

On some systems is better to run :
sudo ldconfig to update the system library cache, otherwise it is requested a reboot of the machine.

Install Czmq

In order to bind the library with the C language is necessary to compile the library Czmq

1.  git clone https://github.com/zeromq/czmq
2.  cd czmq
3.  ./autogen.sh
4.  ./configure --enable-static --disable-shared
5.  make
6.  sudo make install
7.  sudo ldconfig
