assimp cmake mingw-w64 VSCode win10

Question

我正在尝试在opengl中使用assimp，请按照以下此处的构建说明进行操作：在以下环境下为https://github.com/assimp/assimp/blob/master/Build.md：

assimp 5.0.1    
cmake 3.17.2
mingw-w64 with gcc/g++ 8.1.0
VSCode in Win10

我在cmake-gui中尝试过，使用MinGW Makefile，我可以在构建路径中获取一个makefile。

然后我尝试通过mingw32-make使其成功，并使用]停在69％位置>

尽管我可以在构建目录中获得一个“ libassimp.dll”和一个“ libassimp.dll.a”，但是我无法将它们链接到我的项目中。有许多“未定义的对xxxx的引用”错误。

1. 我将.dll放在exe路径中，将.a文件放在lib路径中，所有assimp .h文件都放在了include路径中。
2. VSCode似乎不支持文件名“ libassimp.dll.a”，我必须将其重命名为libassimpdll.a，并在task.json中写入“ -lassimp”。但是存在“未定义的引用”错误。
3. 我试图为VS2017构建asimp，并且我可以获取dll和lib。
4. 我试图直接链接asimp 3.1.1（已正式提供x86 / x64 dll和lib），但也失败了。

所以我的问题是如果有人成功用cmake和mingw-w64构建asimp并将其链接到VSCode Win10中的项目中？

我正在尝试在opengl中使用assimp，请遵循以下构建说明：https://github.com/assimp/assimp/blob/master/Build.md在以下环境下：assimp 5.0.1 cmake 3.17.2 mingw -...
