UnrealBuildTool：ld.lld：错误：无法找到库

Question

操作系统：Manjaro Linux 4.19.28-1-MANJARO

我有一些关于 的ld问题UnrealBuildTool。我对所有虚幻的东西都是新的。

一周前，我发现了一些基于Unreal的开源项目。发布的二进制版本运行良好。但它无法在我的电脑上构建。我认为这是 gcc 链接器找不到assimp library。

所以我设置了环境变量'LIBRARY_PATH'，'LD_LIBRARY_PATH'但是，UnrealBuildTool似乎没有使用本地计算机的 ld 链接器。

有人对此有想法吗？
