Cmake windows10 编译报错

[xuhongv]

编译环境；

• 开发板：ESP32-S2-Kaluga 1.2
• 环境：CMake windows
• IDF版本：release/4.2

使用安装 ESP-IDF 工具安装器，能够正常编译自带的 get-start/helloworld 工程；
但是，无法编译工程 esp32-s2-kaluga-1\examples\camera，提示错误如下：

• 网上答案，路径太长，但是修改了路径长度限制，并没影响；

• 已解决，指定文件夹编译，比如这样。但是希望可以优化下！

idf.py -B D:\ESPRESSIF\Cmake_Windows\esp-idf-4.2\esp-idf\esp-dev-kits\esp32-s2-kaluga-1\examples\camera build
