Cannot find CMakeLists.txt

[mmt-10]

Hi,

I'm using below latest toolchain esp-idf-tools-setup-2.0.exe. When type and execute idf.py build, toolchain displayed error. How do I resolve it?

https://docs.espressif.com/projects/esp-idf/en/latest/get-started/windows-setup.html

C:\ESP-IDF_toolchain\esp-va-sdk\examples\amazon_alexa>idf.py build Note: You are using Python 3.7.4. Python 3 support is new, please report any pro blems you encounter. Search for 'Setting the Python Interpreter' in the ESP-IDF docs if you want to use Python 2.7. Checking Python dependencies... Python requirements from c:\ESP-IDF_toolchain\esp-vas\requirements.txt are satis fied. CMakeLists.txt not found in project directory C:\ESP-IDF_toolchain\esp-va-sdk\ex amples\amazon_alexa

C:\ESP-IDF_toolchain\esp-va-sdk\examples\amazon_alexa>

My command sequence is here. (I make a mistake, I modified below command sequence)

python -m pip install -r c:\ESP-IDF_toolchain\esp-idf\requirements.txt

git clone https://github.com/espressif/esp-va-sdk.git
cd C:\ESP-IDF_toolchain\esp-va-sdk\examples\amazon_alexa

set IDF_PATH=c:\ESP-IDF_toolchain\esp-idf
set ESPPORT=COM20
set AUDIO_BOARD_PATH=c:\ESP-IDF_toolchain\esp-va-sdk\board_support_pkgs\lyrat\audio_board\audio_board_lyrat

I made CMakeLists.txt as below and save it to root directory on amazon_alexa sample project.

CMakeLists.txt

cmake_minimum_required(VERSION 3.5)

include($ENV{IDF_PATH}/tools/cmake/project.cmake) project(alexa)

However, I got below error.

Hi @tatsutaigu CMake is not yet supported in Alexa. You can use the build instructions as documented in this https://github.com/espressif/esp-va-sdk/blob/master/README-Getting-Started.md file.

We will update this issue once CMake support is added to this repository.

Hi, have you CMake ready ? I would like to use with ECLIPSE! Thanks!
