gcc链接Netbeans中的错误

Question

我正在尝试编译一个c文件，该文件使用cygwin在netbeans中打开一个公共对话框。相关代码是：

OPENFILENAME ofn;
char szFileName[MAX_PATH] = "";

ZeroMemory(&ofn, sizeof(ofn));

ofn.lStructSize = sizeof(ofn); // SEE NOTE BELOW
ofn.hwndOwner = hwnd;
ofn.lpstrFilter = "Text Files (*.txt)\0*.txt\0All Files (*.*)\0*.*\0";
ofn.lpstrFile = szFileName;
ofn.nMaxFile = MAX_PATH;
ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
ofn.lpstrDefExt = "txt";

if(GetOpenFileName(&ofn))
{
    // Do something usefull with the filename stored in szFileName 
}

编译时，我得到：

undefined reference to `__imp__GetOpenFileNameA@4'

据我了解，comdlg库没有正确链接，但我无法正确使用它。有谁知道如何将库添加到链接器？
