# Build system for middle-layer layer, that includes:
# - abstractions used on both hardware and software path, such as:
#   - wrappers around analytic operations, CRC, etc. (analytics/, other/)
#   - Huffman Table object implementation and (de)compression flow (compression/)
#   - allocators (common/)
#   - etc.
# - logic related to submission to the accelerator (accelerator/, dispatcher/, util/)
