之前不是讨论的，说是 toolset 向下兼容的么。。#1513

现在 vs2022 的 toolset 不向下兼容低版本 toolset 编译的库了？

build-artifacts 我切到 2019/2022 去 build 了。。如果 toolset >= 14.30.30705 (2022) , 会优先选择高版本 toolset

https://docs.microsoft.com/en-us/cpp/porting/binary-compat-2015-2017?view=msvc-170

Static libraries or object files compiled using the /GL (Whole program optimization) compiler switch or linked using /LTCG (Link-time code generation) aren't binary-compatible across versions, including minor version updates. All object files and libraries compiled using /GL and /LTCG must use exactly the same toolset for the compile and the final link. For example, code built by using /GL in the Visual Studio 2019 version 16.7 toolset can't be linked to code built by using /GL in the Visual Studio 2019 version 16.8 toolset. The compiler emits Fatal error C1047.

貌似开了链接优化的库不是跨版本兼容的

那就仅仅是 lto 的问题咯，这个咋探测区分。。
