It seems you have manually installed NanoGUI. As such, in whatever project you are doing this for, you also need to find Eigen. E.g. with cmake or pkg-config. NanoGUI does not install the Eigen headers.

(the implicit assumption is that if you are installing NanoGUI rather than using it as a submodule, you are also setting NANOGUI_EIGEN_INCLUDE_DIR)

Okay thanks, I simply copied those files
