我正在尝试在Windows上从CLion中作为库来运行graphviz。这需要花费我相当长的时间，我希望这是最后一个障碍。当我运行程序时，我看到以下警告，并且没有出现图形。
Warning: Could not load "C:\Program Files (x86)\Graphviz2.38\bin\gvplugin_pango.dll" - can't open the module
我正在使用MinGW 3.22作为工具链运行CLion。下面是CmakeLists和main.c。不幸的是，我无法注册graphviz论坛，所以希望这里有人能提供一些建议。到目前为止，我尝试了以下方法：
- 安装并使用mingw-64
- 安装GraphViz的旧版本(2.28，当前版本是2.38)
- 在cmakelists.txt中包括gvplugin_pango库
- 更改Graphviz文件夹的权限，允许Everyone完全访问，并测试dot -c可以正常工作
- 将GVBINDIR环境变量设置为明确指向2.38安装
- 尝试在Cmakelists.txt中设置m32(不敢肯定我是否做对了)
