[built error] find wrong python, was not declared in this scope

[jasonppy]

Hi Peter,

I'm trying to build it without Docker, as I need to make MatterSim available to the python in my anaconda envs. But when I cmake it, it's finding the system python, how do I change this?

Besides this, I got an error

Is it related to Depth images? I only downloaded matterport_skybox_images as it is said in the repo that this is minimal requirement for the simulator to work.

Thanks for your time! Jason

I've find a way to help it find the desired python version, by changing cmake -DEGL_RENDERING=ON .. to

cmake -DEGL_RENDERING=ON .. -DPYTHON_LIBRARY=/dir_of_miniconda3/lib/libpython3.8.so \
-DPYTHON_INCLUDE_DIR=/dir_of_miniconda3/include/python3.8/ \
-DPYTHON_EXECUTABLE=/dir_of_miniconda3/bin/python \

and cmake ran successfully, but running make still gives the above error even if I have install depth images and camera parameters

Problem solved by using Docker :)
