Cannot find ORB-SLAM

[KyunghyunLee]

When building the source code,

cmake ..

cannot find orb slam source folder.

When I manually set ORB_SLAM2_LIBRARY and ORB_SLAM2_INCLUDE_DIR , error occurs in

make 

It seems that include folder is not set correctly.

KyunghyunLee,
Have you found any solutions? I am having the same issue.

To configure the location of the orbslam source folder, set ORB_SLAM2_DIR specifically.
You can do this on the command line with -DORB_SLAM2_DIR=/your/desired/location.

The code that is actually trying to find ORB_SLAM can be seen here: https://github.com/jskinn/ORB_SLAM2-PythonBindings/blob/master/cmake_modules/FindORB_SLAM2.cmake
Manually setting ORB_SLAM2_LIBRARY may not set the other variables (such as ORB_SLAM2_LIBRARIES), which may cause linker errors while making even if it configures correctly.

Hi @jskinn

Sorry for the novice question. How do you set the location of ORB SLAM2?

I am getting the same error and have tried to run -DORB_SLAM2_DIR=/your/desired/location. but unsure of whether this should be a standalone command or something adjoined to cmake..

Thank you

Ah, the first part is an argument to cmake.
Try cmake -DORB_SLAM2_DIR=/home/lloyd/orbslam2 .. from the build directory

this did not work for me sadly, it still gives the same error
