我正在尝试使用yocto / bitbake构建配方，但是在构建依赖项时遇到了麻烦。其中一些构建依赖项不会部署到目标上，它们只是在构建过程中被静态链接。因此，我的项目在构建之前需要先构建某些静态库和项目。在配方中将它们指定为“ DEPENDS”，并且可以正确构建它们。
但是，当我的项目尝试在do_configure中运行cmake部分时，cmake输出会抱怨找不到找不到的库。有什么办法可以参考配方中的软件包，以便bitbake可以找到库？还是有更好的方法让cmake知道在哪里可以找到所需的文件？

在do_configure中手动调用cmake并不是一个好习惯。参见the manual：
使用CMake时，您的配方需要继承cmake类，并且您的配方不必包含do_configure任务。您可以通过将EXTRA_OECMAKE设置为传递配方所需的任何所需配置选项来进行一些调整。
OE向cmake的调用中添加诸如路径和工具链文件之类的重要参数的原因，请参见cmake.bbclass。
请尝试删除do_configure并将自定义参数添加到EXTRA_OECMAKE。
