如何在ESP32项目中加入libcurl

Question

我的问题基本上是标题。

我的ESP32项目（我认为重要部分）的目录结构如下：

目录
.VSCODE
组件	curl
	ESP32-Wifi-Manager
构建
Main	Cmakelists.txt
	Main.C
.gitignore
cmakelists.txt
sdkconfig
sdkconfig.old

我为包括libcurl所做的步骤是这些：

1. git clone https://github.com/curl/curl/curl.git （进入组件文件夹）
2. ，然后将2个文件移至curl目录
   -lib/curl_config.h
   -component.mk

请参阅 htttps://github.com.com /nkolban/esp32-snippets/tree/master/curl/build_files 或在相关视频中 https://www.youtube.com/watch？ = tp4oc_kgmgu＆amp; t = 603s 。

我注意到的唯一差异是控制台和我们用来构建的命令。

我们使用“ ESP-IDF 4.4 CMD”和命令“ IDF.PY构建”。

这是控制台中的输出。

在cmakelists.txt中，组件/卷曲/包含行似乎不起作用（例如实用程序）。
如果我们尝试一个绝对路径，而不是$ {cmake_current_source_dir}（请参见下方）稍后在“ project（curl c）”行中的错误。然后，错误说：“项目命令不可脚本可供脚本”。
