VSCode中C程序编译报错：找不到头文件xlsxwriter.h

在VSCode中编写C程序时遭遇编译错误，提示“No such file or directory”。源代码与xlsxwriter.h头文件处于同一目录，已将头文件引入方式从<>改为""，但问题仍未解决。

源代码：

#include "xlsxwriter.h"
 
int main() {
 
    lxw_workbook  *workbook = workbook_new("hello_world.xlsx");
    lxw_worksheet *worksheet = workbook_add_worksheet(workbook, NULL);
 
    worksheet_write_string(worksheet, 0, 0, "Hello", NULL);
    worksheet_write_number(worksheet, 1, 0, 123, NULL);
 
    workbook_close(workbook);
 
    return 0;
}

自动生成的tasks.json：

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: gcc.exe build active file",
            "command": "C:\\cygwin64\\bin\\gcc.exe",
            "args": [
                "-fdiagnostics-color=always",
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "C:\\cygwin64\\bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "compiler: C:\\cygwin64\\bin\\gcc.exe"
        }
    ]
}

• 修正编译工作目录
  当前tasks.json的cwd设为C:\\cygwin64\\bin，gcc会从此目录开始查找头文件，而你的头文件在源代码目录，导致查找失败。可以直接移除cwd配置（默认使用当前文件目录），或者将其改为"${fileDirname}"：

  "options": {
      "cwd": "${fileDirname}"
  }
  

• 显式指定头文件搜索路径
  若不想修改cwd，可在编译参数中添加-I${fileDirname}，告知gcc在当前文件目录下查找头文件，将该参数加入args数组：

  "args": [
      "-fdiagnostics-color=always",
      "-g",
      "-I${fileDirname}",
      "${file}",
      "-o",
      "${fileDirname}\\${fileBasenameNoExtension}.exe"
  ]
  

• 链接xlsxwriter库
  编译xlsxwriter程序必须链接对应库文件，否则后续会出现未定义引用错误。在args末尾添加-lxlsxwriter参数：

  "args": [
      "-fdiagnostics-color=always",
      "-g",
      "-I${fileDirname}",
      "${file}",
      "-o",
      "${fileDirname}\\${fileBasenameNoExtension}.exe",
      "-lxlsxwriter"
  ]
