CMake Error at CMakeLists.txt:19 (find_package): By not providing "Finddescription.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "description", but CMake did not find one. Could not find a package configuration file provided by "description" with any of the following names: descriptionConfig.cmake description-config.cmake Add the installation prefix of "description" to CMAKE_PREFIX_PATH or set "description_DIR" to a directory containing one of the above files. If "description" provides a separate development package or SDK, be sure it has been installed

这个错误信息是在使用CMake构建项目时出现的错误。它指出CMake找不到名为"description"的软件包的配置文件。

要解决这个问题，你可以尝试以下几个步骤：

1. 确保你已经正确安装了名为"description"的软件包。你可以通过软件包的文档或官方网站来获取安装说明。

2. 检查CMakeLists.txt文件中的第19行代码，确认是否正确地使用了find_package命令。确保参数名称和大小写与软件包的配置文件匹配。

3. 检查CMAKE_MODULE_PATH变量的设置。你可以在CMakeLists.txt中添加一行代码，将正确的路径添加到CMAKE_MODULE_PATH变量中，例如：set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "/path/to/description").

4. 如果软件包提供了单独的开发包或SDK，请确保已正确安装。有些软件包可能需要额外的安装步骤或设置环境变量。

通过执行这些步骤，你应该能够解决这个问题并成功构建项目。如果问题仍然存在，可以进一步检查错误信息和相关代码，以寻找其他可能的解决方案。
