LNK2019 cuda::cvtColor and cuda::equalizeHist

Hello! I'm trying to use cuda::cvtColor and cuda::equalizeHist but I get errors as follows:

Error LNK2019 unresolved external symbol "void __cdecl cv::cuda::cvtColor(class cv::debug_build_guard::_InputArray const &,class cv::debug_build_guard::_OutputArray const &,int,int,class cv::cuda::Stream &)" ([email protected]@[email protected]@[email protected][email protected]@[email protected]@[email protected]@@Z) referenced in function "class cv::Mat __cdecl edgedetect(class cv::Mat,double,double)" ([email protected]@[email protected]@@[email protected]@Z) ConsoleApplication2

and likewise for equalizeHist. I guess I'm missing some libs or maybe headers, have you got any idea which ones?
