我正在尝试使用 WiringPi 库通过 clion IDE 运行 c 程序。Hello world 运行良好，因此我可以确保与 pi 的连接已正确建立。但是，当我添加wiringPi-Library #include 并运行wiringPiSetup(); 我收到一条错误消息。

为了解决这个问题，我在 Clion/Preferences/Build、Execution、Deployment/CMake/Build 选项中添加了“-lwiringPi”。然而，这并没有改变什么。也许 CMakeLists.c 中缺少一些东西，但我实际上不知道是什么。

#include <stdio.h>
#include <wiringPi.h>

// Code I want to make running
int main() {
    wiringPiSetup();
    return 0;
}

错误信息：
