 2. Build project - The project uses CMake generator for generating build files. Use `-DENABLE_TESTING=ON` for building test library and test cases and `-DPYTHON_BINDINGS_GEN=ON` for generating python bindings module.

 ### Example usage of the python bindings module
 
 If `-DPYTHON_BINDINGS_GEN=ON` option is given during the CMake build file generation the build tools will build the python bindings, the default name for the python module is `py_sc_aes`.
