Windows11下VS Code中Fortran调用MPI库时mpif.h找不到的问题求助

在Windows 11系统的VS Code中编写并运行Fortran物理模拟程序，需要启用MPI功能。已正确安装Microsoft MPI（MSMPI），在Windows PowerShell中执行set msmpi可查看到正确的环境变量：

MSMPI_BENCHMARKS=C:\Program Files\Microsoft MPI\Benchmarks\
MSMPI_BIN=C:\Program Files\Microsoft MPI\Bin\
MSMPI_INC=C:\Program Files (x86)\Microsoft SDKs\MPI\Include\
MSMPI_LIB32=C:\Program Files (x86)\Microsoft SDKs\MPI\Lib\x86\
MSMPI_LIB64=C:\Program Files (x86)\Microsoft SDKs\MPI\Lib\x64\

程序相关MPI代码片段如下（省略无关部分）：

PROGRAM xyz

USE MPI

...irrelevant...

INCLUDE 'mpif.h'

...irrelevant...

CALL MPI_INIT(ierr)
CALL MPI_COMM_RANK(MPI_COMM_WORLD, rank, ierr)
CALL MPI_COMM_SIZE(MPI_COMM_WORLD, size, ierr)

CALL MPI_REDUCE(var1, var2, 1, MPI_DOUBLE_PRECISION, MPI_SUM, 0, MPI_COMM_WORLD, ierr)

...irrelevant...

CALL MPI_FINALIZE(ierr)

END PROGRAM xyz

运行代码时收到错误：

Error: Can't open include file 'mpif.h'

已参考多个YouTube视频配置VS Code访问MPI库，但部分资料过时，VS Code设置已变更。当前修改后的settings.json内容如下：

{
    "workbench.colorTheme": "Visual Studio Dark",
    "explorer.confirmDelete": false,
    "code-runner.runInTerminal": true,
    "fortran.preferredCase": "uppercase",
    "fortran.linter.compiler": "gfortran",
    "editor.renderWhitespace": "none",
    "editor.accessibilitySupport": "off",
    "editor.tabSize": 6,
    "C_Cpp.default.includePath": [
        "C :\\Program Files\\Microsoft MPI\\MPI\\Include",
        "${workspaceFolder}/**",   
    ],

    "fortran.linter.includePaths": [
        "C:\\Program Files (x86)\\Microsoft SDKs\\MPI\\Include",
        "${workspaceFolder}/**",
    ],
    "fortran.fortls.preprocessor.directories": [
    ],
    "jake.autoDetect": "on",
    "grunt.autoDetect": "on",
    "gulp.autoDetect": "on",
    "json.schemas": [
    ]
}

不确定当前settings.json配置是否正确，仍无法解决找不到头文件的问题。作为编程新手，首次手动调用库，请求帮助解决该问题。
