fatal error: filesystem: No such file or directory about tiny-cuda-nn HOT 4 CLOSED

See my response to the above issue. std::filesystem is a C++17 feature. The lack of support from your compiler suggests a missing flag and/or a too old compiler version.

when i add "experimental" before filesystem
#include <experimental/filesystem>
the errors seems be skipped.
but other more errors show as bellow :

the problem is solved by upgrade cmake to 3.22 on win10 with vs2019

That's great to know, thank you for diagnosing this! I'll have a closer look at which specific cmake version fixes the problem and will update the README accordingly.
