不知道怎么解决

版本是足够新的，汇编器报错就很奇怪了，之前从来没遇到过。难道是 GCC 的代码生成有什么奇怪的特性，导致生成出来的汇编转化成 EXE 出错？

感觉这个问题需要我们做更多测试才有可能解决。建议你先考虑一下更换工具链，比如改用 msys2 的 mingw 工具链，或者直接装 Visual Studio 改用 MSVC 工具链。

MSVC 的版本

首先输入下面指令
cmake -S .. -B . -DCMAKE_BUILD_TYPE=Debug -G "Visual Studio 17 2022"
得到下面结果，

虽然不知道这些文件是什么，但似乎不影响文件的构建
之后进行编译
输入指令

cmake --build . --config Debug --target dandelion --parallel 8

得到下面结果

适用于 .NET Framework MSBuild 版本 17.11.9+a69bbaaf5

有两处一样的报错

cl : 命令行 error D8021: 无效的数值参数“/Wa,-mbig-obj”

查找资料显示出错原因是 Visual Studio 的 cl.exe 编译器不支持 GCC/MinGW 常用的 -Wa,-mbig-obj 参数。这个参数通常用于处理大对象文件，特别是在某些库（如 fmt 和 assimp）的编译中。但它是针对 GCC 和 MinGW 编译器的参数，而 cl.exe 作为 MSVC 的编译器，不认识这个参数。

这该怎么处理
