Update cmake min to 3.14 (#4175)
3.14 is used and tested by linux mini-product

to fix

```
CMake Error at CMakeLists.txt:4 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

wasm-micro-runtime as ESP-IDF component

You can build an ESP-IDF project with wasm-micro-runtime as a component:

  • Make sure you have the ESP-IDF properly installed and setup

  • In particular have the following paths set:

    • WAMR_PATH to point to your wasm-micro-runtime repository
    • IDF_PATH to point to your ESP-IDF
    • source $IDF_PATH/export.sh
  • Create a new project, e.g.: idf.py create-project wamr-hello

  • In the newly created project folder edit the CMakeList.txt:

    cmake_minimum_required(VERSION 3.14)
    
    include($ENV{IDF_PATH}/tools/cmake/project.cmake)
    
    set (COMPONENTS ${IDF_TARGET} main freertos esptool_py wamr)
    
    list(APPEND EXTRA_COMPONENT_DIRS "$ENV{WAMR_PATH}/build-scripts/esp-idf")
    
    project(wamr-hello)
    
  • Develop your project in it's main component folder.

You can find an example here.

  • Set target platform: idf.py set-target esp32c3
  • Build: idf.py build
  • Flash: idf.py flash
  • Check the output: idf.py monitor
