Usage: cargo make [TASK]
Available Tasks:
  cpp_wrapper - Build the C++ wrapper.
  java_wrapper - Build the Java wrapper.
  python_wrapper - Build the Python wrapper.
  all_wrappers - Build all wrappers.
You can pass additional arguments to each build task by appending them after the task name.
For example: cargo make cpp_wrapper --release
