idf.py menuconfig時出現錯誤CMake Error at C:/Users/nomo9/esp/esp-idf/tools/cmake/utilities.cmake:108 (target_sources):Cannot specify sources for target "mqtt_websocket_secure.elf" which is notbuilt by this project.Call Stack (most recent call first):CMakeLists.txt:12 (target_add_binary_data)
問題說明:
無法為 “mqtt_websocket_secure.elf” 目標指定源文件，因為這個目標不是由這個專案構建的。這種問題通常是由於 CMakeLists.txt 文件配置不正確或文件結構問題所導致的。
錯誤信息提到了 target_add_binary_data 函數在 CMakeLists.txt 的第12行有問題。這個函數用於將二進位數據（在這個案例中是 PEM 文件）添加到構建目標中。如果 mqtt_websocket_secure.elf 目標不存在或者在這個階段還沒有被定義，就會導致這個錯誤。
解決方式:
原始CMakeLists.txt
# The following four lines of boilerplate have to be in your project's CMakeLists
# in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.16)
# (Not part of the boilerplate)
# This example uses an extra component for common functions such as Wi-Fi and Ethernet connection.
set(EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/examples/common_components/protocol_examples_common)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(websockets)
target_add_binary_data(mqtt_websocket_secure.elf "main/mqtt_eclipseprojects_io.pem" TEXT)
替換成
# The following four lines of boilerplate have to be in your project's CMakeLists

cmake_minimum_required(VERSION 3.16)
# (Not part of the boilerplate)
# This example uses an extra component for common functions such as Wi-Fi and Ethernet connection.
set(EXTRA_COMPONENT_DIRS $ENV{IDF_PATH}/examples/common_components/protocol_examples_common)
include($ENV{IDF_PATH}/tools/cmake/project.cmake)
get_filename_component(ProjectId ${CMAKE_CURRENT_LIST_DIR} NAME)
string(REPLACE " " "_" ProjectId ${ProjectId})
project(${ProjectId})
