What exact conditions are there to running ./cursor-7801■■■6824585b7f2721900066bc87c4a09b740?
I have two environments which are binary identical as far as libstdc++ goes also /usr is identical between the two systems.
I would like to know in better detail what exact preconditions cursor is trying to validate because the error message doesn’t tell me much on what is wrong.

- the kernel config is identical on the two machines

On one machine the /lib is a symlink to /usr/lib and on the other /lib is a standalone system lib that can be used without /usr being mounted. I suspect this might be the problem but not knowing what cursor expects to find in either of those places makes this very difficult to debug.
I have also tried to run with a minimal environment variables (env -i bash) but no difference.
Running strace ./cursor-0781e811de386a0c5bcb07ceb259df8ff8246a50 on the two machines reveals nothing suspicious`
