树莓派 PICO 的 cmake 文件编码问题
Issues with encoding for cmake files for raspberry PICO
我不确定到底发生了什么，我使用的是 cmake 3.21.1 并拥有适用于 visual studio 的最新 2019 构建工具，但这是 nmake 的输出：
AR10B2~1.EXE: error: CMakeFiles/Generated.dir/Generated.c.obj: No such file or directory

我遇到了同样的问题，在这里找到了答案
卸载 CMAKE cmake-3.21.2 并安装 cmake-3.20.5
我的解决方案是安装 MinGW 工具链作为生成器。它还解决了 ELF2UF2 在任何完全清理的情况下的构建问题，并绕过了使用任何 Visual Studio 2019 构建工具的需要。我在虚拟机中测试了这个，这里安装了干净的 windows：https://youtu.be/BAoTBg8MJJ4
我不确定到底发生了什么，我使用的是 cmake 3.21.1 并拥有适用于 visual studio 的最新 2019 构建工具，但这是 nmake 的输出：
AR10B2~1.EXE: error: CMakeFiles/Generated.dir/Generated.c.obj: No such file or directory
如您所见，cmake 文件存在某种编码问题。这是一个空的 hello world 项目。
