fatal error: Core: No such file or directory

Hello everyone, I encountered a error as the title in the compilation (instant-ngp$ cmake --build build --config RelWithDebInfo -j 16) I work on RTX 3090 CUDA 11.6 Ubuntu 20.04. The error log is: In file included from /home/lixing/src/FREN/instant-ngp/include/neural-graphics-primitives/common.h:35, from /home/lixing/src/FREN/instant-ngp/include/neural-graphics-primitives/camera_path.h:17, from /home/lixing/src/FREN/instant-ngp/src/camera_path.cu:15: /home/lixing/src/FREN/instant-ngp/dependencies/eigen/Eigen/Dense:1:10: fatal error: Core: No such file or directory 1 | #include "Core" | ^~~~~~ compilation terminated. In file included from /home/lixing/src/FREN/instant-ngp/include/neural-graphics-primitives/common.h:35, from /home/lixing/src/FREN/instant-ngp/include/neural-graphics-primitives/common_device.cuh:18, from /home/lixing/src/FREN/instant-ngp/src/common_device.cu:15: /home/lixing/src/FREN/instant-ngp/dependencies/eigen/Eigen/Dense:1:10: fatal error: Core: No such file or directory 1 | #include "Core" | ^~~~~~

I have no idea how to solve it as I am not familiar with it, any idea or help is appreciated. Thanks!

By the way, I have tried the solutions on: https://stackoverflow.com/questions/23284473/fatal-error-eigen-dense-no-such-file-or-directory, but seems it doesn't work.
