MaixPy project build error for TensorFlow Lite Micro Hello world example

[marconi1964]

Describe the bug I tried to build MaixPy with TensorFlow Lite Micro hello world example, but fail in finding *.h in MaixPy build. I am not familiar with cmake build, does not know how to add "include" directory in source directory CMakeLists.txt. The (partial of) CMakeLists.txt in source directory is listed below.

A clear and concise description of what the bug is.

To Reproduce Steps to reproduce the behavior:

1. Build TensorFlow Lite Micro (TFLM) source code, and copy source code from TFLM to maixpy directory.

   
   # download MaixPy
   $ git clone https://github.com/sipeed/maixpy
   # Create a new directory for TFLM hello world
   $ mkdir -p maixpy/projects/TFLM_hello_world
   # Copy MaixPy hello world template directory to TLFM hello world
   $ cp -r maixpy/projects/hello_world/ maixpy/projects/TLFM_hello_world/
   # download TensorFlow
   $ git clone https://github.com/tensorflow/tensorflow.git
   $ cd tensorflow
   # TensorFlow Lite Micro build source files structure
   $ make -f tensorflow/lite/micro/tools/make/Makefile TARGET=riscv32_mcu generate_hello_world_make_project
   $ cd tensorflow/lite/micro/tools/make/gen/riscv32_mcu_riscv32_mcu_micro/prj/hello_world/make
   $ ls -l
   total 40

   -rw-r--r-- 1 ubuntu ubuntu 11291 Apr 20 07:43 Makefile
   -rw-r--r-- 1 ubuntu ubuntu   810 Apr 20 07:43 README_MAKE.md

   drwxr-xr-x 6 ubuntu ubuntu  4096 Apr 20 07:43 third_party

$ cp -r ./ ~/maixpy/projects/TFLM_hello_world

2. Modify source directory CMakeLists.txt "Add source files", based on TFLM Makefile content (SRCS:= \.....)

$ cd maixpy/TFLM_hello_world/main/ $ cat CMakeLists.txt ############### Add include ################### list(APPEND ADD_INCLUDE "." )

list(APPEND ADD_PRIVATE_INCLUDE "")

3. MaixPy build and error occurs

uset python project.py rebuild --verbose to see what dependence or something wrong
