执行cmake ..时无法找到PugiXml配置文件，安装libpugixml-dev无效求解决

执行cmake ..时出现如下错误：

Could not find a package configuration file provided by "PugiXml" with any
of the following names:

PugiXmlConfig.cmake
pugixml-config.cmake

Add the installation prefix of "PugiXml" to CMAKE_PREFIX_PATH or set
"PugiXml_DIR" to a directory containing one of the above files. If
"PugiXml" provides a separate development package or SDK, be sure it has
been installed.

已通过sudo apt install libpugixml-dev安装开发包但问题未解决，可尝试以下方案：

• 手动指定配置文件路径
  先查找系统中已安装的pugixml配置文件位置：

  find /usr -name "pugixml-config.cmake" -o -name "PugiXmlConfig.cmake"
  

  找到路径后，在执行cmake时指定PugiXml_DIR：

  cmake .. -DPugiXml_DIR=/path/to/pugixml/cmake/directory
  

  或者将配置文件所在的父目录添加到CMAKE_PREFIX_PATH：

  cmake .. -DCMAKE_PREFIX_PATH=/path/to/pugixml/parent/directory
  

• 从源码编译安装PugiXml
  若apt包未提供正确的CMake配置文件，直接源码编译安装：

  1. 克隆源码：

     git clone https://github.com/zeux/pugixml.git
     cd pugixml
     

  2. 编译安装：

     mkdir build && cd build
     cmake .. -DBUILD_SHARED_LIBS=ON
     make -j$(nproc)
     sudo make install
     

  安装完成后，CMake默认会在/usr/local/lib/cmake/pugixml/找到配置文件。

• 调整项目CMakeLists.txt
  检查项目中的find_package调用，若原代码是find_package(PugiXml)，尝试改为小写的find_package(pugixml)，匹配apt安装的配置文件名。
