bitbake - qpid-cpp-1.39.0 的 Bitbake 构建失败

Question

我必须先说我对 Yocto/Bitbake、make、cmake、autoconf 等知之甚少。

我有一个用 C++ 编写的应用程序，但我一直无法构建。我遇到的问题是我无法在 Yocto/Bitbake 中构建一些依赖项。该应用程序依赖于以下库：

Paho-MQTT ( https://github.com/eclipse/paho.mqtt.c.git ) Jansson JSON 解析器 ( http://www.digip.org/jansson/releases/jansson-2.10.tar.gz ) Apache QPID C++ ( https://www-us.apache.org/dist/qpid/cpp/1.39.0/qpid-cpp-1.39.0.tar.gz )

运行 apache qpid 的 bitbake 配方时，我收到以下错误：

CMake Error at src/CMakeLists.txt:84 (message):
|   Can't find amqp 0-10 spec for framing code generation

我不知道如何克服这个错误。

我在 Macbook 上运行 Docker/Yocto，并按照说明安装并运行所有内容。正在为运行 mLinux 版本 4.1.6 的 Multitech Conduit 网关编译应用程序（和相关库）。我按照http://www.multitech.net/developer/software/mlinux/mlinux-building-images/building-a-custom-linux-image/上的说明下载和构建 mLinux 4.0 及更高版本的默认映像。

我找不到用于构建 qpid-cpp-1.39.0 的现有配方。我能够找到 qpid_0.20 的配方（http://git.yoctoproject.org/cgit/cgit.cgi/meta-cloud-services/tree/meta-openstack/recipes-extended/qpid/qpid_0.20。 bb?h=master），我试图修改它以支持 qpid-cpp-1.39.0。对配方运行 bitbake 时，我收到以下输出：

知道三天前我刚刚开始学习 Yocto/Bitbake，我希望那里的人可以帮助我确定问题所在，以便我可以为 mLinux 编译 apache qpid-cpp-1.39.0 库。

根据find_file文档：

CMake 变量 CMAKE_FIND_ROOT_PATH 指定一个或多个目录要附加到所有其他搜索目录。这有效地“重新扎根”了给定位置下的整个搜索。作为 CMAKE_STAGING_PREFIX 的后代的路径被排除在此重新生根之外，因为该变量始终是主机系统上的路径。默认情况下 CMAKE_FIND_ROOT_PATH 为空。

并且由于cmake从环境调用bitbake实际上是一个交叉编译，所以这个变量也应该被忽略。我添加了一个对我有用的补丁files/0001-Qpid-cross-compile.patch：
