Additional context
Add any other context about the problem here.
I think somewhere the path to the lib file doesn't resolve correctly or maybe something different.
LINK : warning LNK4044: unrecognized option '/fopenmp'; ignored
LINK : fatal error LNK1181: cannot open input file 'mujoco210.lib'
error: command 'D:\dev\VC\Tools\MSVC\14.29.30133\bin\HostX86\x86\link.exe' failed with exit code 1181
First I think for VC it must /openmp
https://docs.microsoft.com/en-us/cpp/build/reference/openmp-enable-openmp-2-0-support?view=msvc-170
But it was ignored anyway.
So the root cause
