首先你的理解有问题，你构建时的目标架构是 x86 而非 x64 通常和 PowerShell 的版本无关，它应当总是 64 位的（Windows 10 和 PowerShell 的 32 位版本非常少见）。

我看到图中最后的输出是

NMAKE: fatal error\n

这意味着 CMake 此时生成了 nmake 工程而不是 Visual Studio 解决方案，这不是我们推荐的构建方式。建议清空 build 目录下的所有文件，并按照如下方法尝试指定生成 VS 工程文件：

CMake 的构建后端称为 generator 。根据你自己的 VS 版本，请参考官方文档 Visual Studio 16 2019 (VS 2019) 或 Visual Studio 17 2022 (VS 2022) ，用 -G 参数设置 generator 为 Visual Studio，用 -A x64 参数设置目标平台为 x64。
