vscode 无法识别 constexpr

Question

提示如下：

c_cpp_properties.json以按如下配置：

{
    "configurations": [
        {
            "name": "Mac",
            "includePath": [
                "${workspaceFolder}/**",
                "/Library/Developer/CommandLineTools/usr/include",
                "/Library/Developer/CommandLineTools/usr/lib/clang/11.0.3/include",
                "/usr/local/include"
            ],
            "defines": [],
            "macFrameworkPath": [
                "/System/Library/Frameworks",
                "/Library/Frameworks"
            ],
            "compilerPath": "/usr/bin/clang++",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "clang-x64",
            "compileCommands": "${workspaceFolder}/build/compile_commands.json"
        }
    ],
    "version": 4
}

用vscode自带的debug，无异常，用cmake编译运行，也无异常。
推测应该是单纯的vscode识别不出来，如何解决？

请大佬解答，感激不尽！
