我正在尝试为一个使用libmariadb的C++应用程序制作一个食谱。在开发时，我使用的是vcpkg，但现在我想使用Yocto。
下面是应用程序_1.0.0.bb文件：
# Metadata
SUMMARY = "Customer API Backend"
DESCRIPTION = "Customer API in C++ using gRPC"
# License is closed, no checksum to avoid warnings
LICENSE = "CLOSED"
LIC_FILE_CHKSUM = ""
DEPENDS = "protobuf protobuf-c protobuf-native grpc grpc-native openssl mariadb poco"
SRCREV = "${AUTOREV}"
SRC_URI = "git://git@gitlab.com/software/projects/embedded/application.git;protocol=ssh;branch=master;"
S = "${WORKDIR}/git"
inherit pkgconfig cmake下面是CMake部分，它给Yocto带来了问题：
find_package(unofficial-libmariadb CONFIG REQUIRED)
find_package(Poco REQUIRED COMPONENTS Data DataMySQL)
target_link_libraries(database_api
PRIVATE
unofficial::libmariadb
Poco::DataMySQL
)我在配置步骤（CMake）中收到此错误消息：
CMake Error at src/libraries/external_interfaces/database_api/CMakeLists.txt:20 (find_package):
Could not find a package configuration file probided by
"unofficial-libmariadb" with any of the following names:
unofficial-libmariadbConfig.cmake
unofficial-libmariadb-config.cmake
Add the installation prefix of "unofficial-libmariadb" to CMAKE_PREFIX_PATH
or set "unofficial-libmariadb_DIR" to a directory containing one of the
above files. If "unofficial-libmariadb" provides a separate development
package or SDK, be sure it has been installed.我尝试将mariadb-native添加到bitbake配方上的DEPENDS中，但随后收到以下错误消息when configuring mariadb-native '：
CMake Error at /home/oe-core/build/tmp/work/x86_64-linux/mariadb-native/10.7.5-r0/recipe-sysroot-native/usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:230 (message):

(Required is at least version "3.3.24")

好的，我通过使用最近版本的mariadb食谱+ vcpkg mariadb端口补丁找到了它：
1.对于mariadb本地版本：在您所在层的recipes-dbs/mysql/文件夹中添加mariadb-native_%.bbappend：
另一种选择是使用最新的mariadb-native_%.bb方法，因为它已经包含在内了。如果像我一样，你有10.7.4或其他版本，bbappend是必需的。
1.对于非官方mariadb目标：使用Yocto的
devtoolonmariadb方法，我刚刚复制了libmariadb的vcpkg端口所具有的补丁（可以在以下位置找到：https://github.com/microsoft/vcpkg/tree/master/ports/libmariadb）。最重要的是修改libmariadb/CMakeLists.txt（但从mariadb配方来看，这是libmariadb/libmariadb/CMakeLists.txt，因为这是一个更高的存储库层）。此修补程序导出非官方的libmariadb，并且还使用非官方的：：命名空间。这使我的项目兼容。
