    # Add catch unit test framework
    # TODO Use gtest as it is the team recommendation
    #      Unfortunately gtest is very hard to setup as not binary distributed
    #      catch is only one header so it is very easy
    # Catch can be downloaded from:
    # https://raw.github.com/philsquared/Catch/master/single_include/catch.hpp
    # Then append the download folder to the CMAKE_INCLUDE_PATH variable or
    # copy it in a standard location (/usr/include on most linux distribution).
