* Mandatory dependencies:
* libfftw
* Optional requirements:
* libsdrgui: for real-time plotting. Download it here: https://github.com/suttonpd/libsdrgui
* srsgui: for real-time plotting. Download it here: https://github.com/srslte/srsgui
* VOLK: if the VOLK library and headers are detected, they will be used for accelerating some signal processing functions.
* Matlab/Octave: if found by CMake, MEX files will also be generated and installed. If you find any compilation issue with MEX and you don't need them, pass -DDisableMex=ON to cmake to disable them.
