###### Build FMCOMMS2 based SDR Hardware support (OPTIONAL):
Install [libiio] (https://github.com/analogdevicesinc/libiio.git

~~~~~~
$ git clone https://github.com/analogdevicesinc/libiio.git
$ cd libiio
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
$ sudo ldconfig
$ git clone https://github.com/analogdevicesinc/libad9361-iio.git

Then configure the gnss-sdr to build the `Fmcomms2_Signal_Source`:
~~~~~~
$ cmake -DENABLE_FMCOMMS2=ON ../
$ make
$ sudo make install
