mingw-w64 & CLion 无法使用 assimp 成功编译项目

Question

使用CLion & mingw-w64(7.2.0) 编译https://github.com/CasterKKK/OpenGLStarter，得到如下错误：

但如果我用 Visual Studio 2017 打开并编译它，它工作正常...

这是 CLion 的设置： 我使用命令行cmake -G"Visual Studio 15 2017 Win64" ..编译代码，它工作正常，但我无法在CLion中设置Visual Studio，因为它找不到C:\Program Files (x86)\Microsoft Visual Studio\2017\Community，即使我的VS 2017就在那里，这真的很奇怪......

问题是 Github 上的项目从未使用 mingw 构建，因此您看到了这些问题。最好坚持使用 VS 或 clang 编译器。
