During the process of cmake configuration, there’s an error stating “error in configuration process, project files may be invalid”. It would be deeply appreciated if anyone can help me out.

More information is needed here. Specifically, the build errors for Eigen. However, I suggest engaging with libigl upstream since it’s more likely that it is related to something there rather than CMake itself (at least without more information).

Thank you for your help. After I download it again, it can be configured normally.

Which one you download again? Cmake or Libigl?
