CMake Deprecation Warning at CMakeLists.txt:16 (cmake_policy):
The OLD behavior for policy CMP0017 will be removed from a future version
of CMake.
The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

您发布的示例输出显示构建系统正在寻找“源”目录以及要构建的文件。在本例中为 .cpp 文件。
你没有说你使用的是哪个版本的 micro:bit。以下建议对我在 Debian 上使用 v1 版本的 micro:bit 有用。
从 GitHub 上的兰卡斯特大学存储库下载 micro:bit 示例并解压：
https://github.com/lancaster-university/microbit-samples
microbit-samples-master 目录中有一个示例 main.cpp 文件和 .json 文件。examples 目录中还有其他示例 .cpp 文件。
在 microbit-samples-master 目录中：
yt target bbc-microbit-classic-gcc-nosd
yt clean
yt build
.hex 文件位于以下位置：
microbit-samples-master/build/bbc-microbit-classic-gcc/source
