【问题描述】：
我用 CLion 开始了一个新的 C 项目，并想使用 MPI。因为我在 Windows 上，所以我安装了 MS-MPI（MSMPI 和 SDK），并且我的 CMakeLists.txt 如下：
cmake_minimum_required(VERSION 3.10)
project(ppc)
set(CMAKE_C_STANDARD 11)
find_package(MPI REQUIRED)
add_executable(ppc main.c)
target_link_libraries(main PRIVATE MPI::MPI_C)
问题是每当我尝试导入/重新加载项目时，都会收到以下错误：

我的文件有什么问题？
