Issue with installing flightmare

[spnd-vig]

**I am getting this error while entering into flightlib directory and issuing pip install . command:

(This is last few lines of the output)**

File "/tmp/pip-install-p36rsui7/atari-py_73d120c27bd94c5caa27670917c355d6/setup.py", line 21, in run
subprocess.check_call(['cmake', '--build', '.'], cwd=cwd)
File "/usr/lib64/python3.10/subprocess.py", line 369, in check_call
raise CalledProcessError(retcode, cmd)
subprocess.CalledProcessError: Command '['cmake', '--build', '.']' returned non-zero exit status 2.
[end of output]

note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure

× Encountered error while trying to install package.
╰─> atari-py

note: This is an issue with the package mentioned above, not pip.

I resolved that error by installing python310-devel. The issue was that gcc wasnt able to locate Python.h.

But now i am stuck here:

Running setup.py install for flightgym ... error
error: subprocess-exited-with-error
