在CLion上找不到带有MS-MPI的MPI (缺少: MPI_C_FOUND MPI_CXX_FOUND)

Question

我用CLion开始了一个全新的C项目，并且想要使用MPI。由于我在Windows上，所以我安装了MS-MPI ( MSMPI和SDK)，并且我的CMakeLists.txt如下所示：

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，我都会收到以下错误：

我的文件有什么问题？

尝试在您的project声明后添加以下内容：

enable_language(Fortran)
