Question

how to set path in Microsoft visual studio

Answer 1

You have a couple of options:

You can add the path to the DLLs to the Executable files settings under Tools > Options > Projects and Solutions > VC++ Directories (but only for building, for executing or debugging here)

You can add them in your global PATH environment variable

You can start Visual Studio using a batch file as I described here and manipulate the path in that one

You can copy the DLLs into the executable file's directory :-)
