Use std::filesystem::canonical to turn the path into an absolute path with all .. removed (reference):
auto path = std::filesystem::canonical("/root/home/../opt/.");
Gives you:
"/root/opt"
You can also use from this function.
std::cout << std::filesystem::path("/root/home/../opt/.").lexically_normal() << std::endl;
