BB配方中的CMake

Question

我正在为cpsumon开发一个OpenEmbedded层，这是一个用C编写的工具，用于监控Corsair AXi电源单元(电源单元)。

我的图层的代码可以在https://github.com/bernardoaraujor/meta-cpsumon上找到

我使用Make和CMake的经验非常有限，我很难理解以下错误：

据我所知，| make: *** No rule to make target 'install'. Stop.意味着BitBake正在尝试使用--target install执行cmall，而由于某种原因，make不能执行install任务。对吗？

我不明白这个问题是必须在CMakeLists.txt还是cpsumon_git.bb中解决。任何帮助都是非常感谢的！

Answer 1

cpsumon的CMake脚本实际上并不在任何地方安装库，因此生成的makefile不包含install目标。

因此，当do_install任务执行make install时，您会收到来自make的错误消息

make: *** No rule to make target 'install'.
