使用G2O库时编译错误

编译时出现如下错误：

CMake Error at CMakeLists.txt:11 (find_package): 
By not providing "FindG2O.cmake" in CMAKE_MODULE_PATH this project has 
asked CMake to find a package configuration file provided by "G2O", but 
CMake did not find one. 

Could not find a package configuration file provided by "G2O" with any of 
the following names: 
G2OConfig.cmake 
g2o-config.cmake 

解决办法：

修改CMakeLists.txt文件，

将 list( APPEND CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake_modules ) 

修改为 list( APPEND CMAKE_MODULE_PATH /home/libs/g2o/cmake_modules )  路径为g2o安装位置
