CMake C++ 包含要进行项目的静态系统库 - 如何

Question

我是 C++ 和 CMake 项目的新手。 我（使用 CLion）编写了使用 mysql 连接器的非常简单的应用程序。 这需要安装在系统libmysqlcppconn-dev 。 这在我构建它的系统上没有问题，但是如果我想在其他系统上执行它，它会失败，因为它需要共享库。 我想将该库包含到我的项目中。 为此，在我的项目中，我创建了文件夹lib/static并复制了文件。

$ tree lib/static
lib/static
├── libmysqlcppconn.a
└── libmysqlcppconn-static.a

安装开发库后的这些文件位于：

/usr/lib/x86_64-linux-gnu/libmysqlcppconn-static.a
/usr/lib/x86_64-linux-gnu/libmysqlcppconn.a
/usr/lib/x86_64-linux-gnu/libmysqlcppconn.so

现在在我的CMalke.lists 中我添加了：

#find_library(MYSQLCPP mysqlcppconn-static lib/static/)

add_library(MYSQLCPP STATIC IMPORTED)
set_property(TARGET MYSQLCPP PROPERTY IMPORTED_LOCATION ${PROJECT_SOURCE_DIR}/lib/static/libmysqlcppconn-static.a)

link_directories(lib/static)

target_link_libraries(${project_name} oatpp pthread curl ${MYSQLCPP})

但这不会编译

[100%] Linking CXX executable ../dist/bin/smsapiclient
/usr/bin/ld: CMakeFiles/smsapiclient.dir/src/App.cpp.o: in function `MyController::rootPOST(oatpp::data::mapping::type::String const&)':
/home/marcin/projects/smsapiclient/src/controller/MyController.hpp:61: undefined reference to `get_driver_instance'
collect2: error: ld returned 1 exit status

如果我取消注释find_library()函数并注释add_library() set_property()我收到那个错误

[ 98%] Linking CXX executable ../dist/bin/smsapiclient
/usr/bin/ld: /home/marcin/projects/smsapiclient/lib/static/libmysqlcppconn-static.a(mysql_client_api.cpp.o): in function `sql::mysql::NativeAPI::LibmysqlStaticProxy::options(MYSQL*, mysql_option, void const*)':
(.text+0x4c4): undefined reference to `mysql_options'

一切都适用于共享系统库，但我想将其添加到可执行文件中以使其不依赖于其他系统。

我应该如何正确地将静态库包含到我的项目中？ 感谢您提前提供帮助。

使用系统库构建 ii 后，ldd 显示：
