Subject: [PATCH] FindFilesystem: Eliminate Win32 warning

Using `printf("%s")` with a `std::filesystem::path` on Win32 will
cause a compile warning, because `std::filesystem::path::value_type`
is technically `wchar_t`.

The warning is harmless, but by using iostream to print the value
on `std::cout` instead, the code compiles without warnings.
