#TODO: Include layer for Google's FlatBuffer
    # source: git clone https://github.com/google/flatbuffers.git
    # within "FlatBuffers" dir, "cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release ." (for Mac) find Linux version
    # compile FlatBuffers, using "make"
    # OPTIONAL TEST RUN: "./flattests"
    # move flatc exec to usr/local/ (also contains cmake) "sudo mv flatc /usr/local/"


#Install the dependencies required for the build
    # build-essential (GNU Compiler)
    # libstdc++-11-dev (C++ std libraries)
    # wget to make a request for Cmake
    # git to retreive the ENet library
    # autoconf and libtool (dependency of autoconf)

# "apt-get clean" will delete the leftover .deb files from the install
# "rm -rf "var/lib/apt/lists/*" deletes the package list downloaded by "apt-get update"

# Delete the old compressed cmake.tar.gz
