我认为我已经找到解决问题的方法（不确定是否是***的方法）。我在 CMake邮件列表中发现了类似的问题，并提出了答案似乎可行：。

I think I have found a solution to my issue (Not sure whether it is the best one). I have found similar question in the CMake mailing list and the answer proposed there seems to work: .

看来，这种情况可能是由于自己的MinGW工具集没有正确的内置包含目录引起的。无论如何，对我来说，解决方案是将此行添加到我的工具链文件中：

It seems that this situation could be caused by the own MinGW toolset not having the right built-in include directories. Anyways, the solution for me was to add this line into my toolchain file:

set(CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES /usr/lib/gcc/${TOOLCHAIN_PREFIX}/7.3-posix)
