解决方法 #

方法1：指定CMake跳过重复查找glog #

执行cmake时添加参数，让COLMAP直接使用系统已找到的glog，避免Ceres的查找脚本重复创建目标：

cmake .. -GNinja -DCMAKE_DISABLE_FIND_PACKAGE_Glog=ON

方法2：重新编译Ceres并绑定系统glog #

如果是手动编译的Ceres，重新编译时指定系统glog的路径，让Ceres直接链接已有的库：

# 进入Ceres源码目录
mkdir -p build && cd build
cmake .. -DGLOG_INCLUDE_DIR=/usr/include -DGLOG_LIBRARY=/usr/lib/x86_64-linux-gnu/libglog.so
make -j$(nproc)
sudo make install

完成后重新执行COLMAP的cmake配置。

方法3：清理冲突的glog版本 #

如果系统中存在多个glog安装（比如系统包+手动编译版本），卸载手动安装的版本，保留系统默认包：

sudo apt remove libgoogle-glog-dev
sudo apt install --reinstall libgoogle-glog-dev

之后重新运行COLMAP的cmake命令。
