G2o_DIR path. Not accepting #7

``CMake Error at CMakeLists.txt:7 (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

Add the installation prefix of "G2O" to CMAKE_PREFIX_PATH or set "G2O_DIR" to a directory containing one of the above files. If "G2O" provides a separate development package or SDK, be sure it has been installed.

I used following lines but new error is encountered

LIST( APPEND CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake_modules )
SET( G2O_ROOT /home/chaien/VR/PLSLAM/g2o )
FIND_PACKAGE( G2O )

@chaiein how can you solve this problem. I added three line into camkelists, this error was still on. LIST( APPEND CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake_modules ) SET( G2O_ROOT /home/cc/test/g2o-master ) FIND_PACKAGE( G2O )

Your G2O_INCLUDE_DIR is not in the list. To solve this problem, you can do a system wide installation. Run sudo make install from g2o build directory

Then you will see g2o is added to /usr/local/include/

Add a folder calls "cmake_module" in pl-slam, and touch a file "FindG2O.cmake" in the folder, the problem can be solved.

This is "FindG2O.cmake": https://github.com/gaoxiang12/slambook/blob/master/ch6/g2o_curve_fitting/cmake_modules/FindG2O.cmake
