我试图使用VSCode在Linux RT内交叉编译一个C代码和CMake。但是我遇到了一个错误，这是由于将（.so）文件与项目链接时出错。我尝试了许多解决方案，但未能运行该任务。我的代码如下所示：

`     #include<stdio.h>
      #include"/home/admin/helloworld/src/NIDAQmx.h"

      TaskHandle taskHandle=0;
      int ret=0;

      void main()
      {
      printf("Hello world");
      ret=DAQmxCreateTask("task",&taskHandle);
      printf("Return for creating task is %d\n",ret);
      DAQmxStopTask (taskHandle);
      DAQmxClearTask(taskHandle);
      printf("Task closed ");

      }               `

运行任务时出错

`[ 50%] Linking C executable bin/helloWorld

 *  The terminal process "/bin/bash '-c', 'make'" failed to launch (exit code: 2).

我修改了我的CMakeLists.txt如下：

`     cmake_minimum_required(VERSION 3.7.2)
      # project settings
      project(helloWorld VERSION 0.1.0)
      set(CMAKE_RUNTIME_OUTPUT_DIRECTORY bin)
      set(CMAKE_GENERATOR "Unix Makefiles")
      # executable settings
      add_executable(helloWorld ../src/helloWorld.c)
      set(CMAKE_BUILD_TYPE Debug)
      LINK_LIBRARIES(NIDAQmx ../src/libnidaqmx.so)
                             `

如果我删除了与NIDAQmx代码正常工作相关的元素。
