编译esp-at源码时出错

[Jarml0x0F]

在编译esp-at源码时，出现如下的错误提示;

Perhaps the $srctree environment variable (which was unset) is set incorrectly. Note that the current value of $srctree is saved when the Kconfig instance is created (for consistency and to cleanly separate instances). Also note that e.g. $FOO in a 'source' statement does not refer to the environment variable FOO, but rather to the Kconfig Symbol FOO (which would commonly have 'option env="FOO"' in its definition).

提示未能找到该文件，看输出的日志，个人认为是文件路径中斜杠符号丢失所致，请问这个该如何解决呢。

这个需要手动修改几行 esp-idf 代码； 参见 https://github.com/espressif/esp-at/issues/232
