Error compiling CUDA from Command Prompt

For new Visual Studio cl.exe is present in path => C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.23.28105\bin\Hostx64\x64

x64 is for 64bit

x86 is for 32bit

You will need to add the folder containing the "cl.exe" file to your path environment variable. For example:

C:\Program Files\Microsoft Visual Studio 10.0\VC\bin

Edit: Ok, go to My Computer -> Properties -> Advanced System Settings -> Environment Variables. Here look for "PATH" in the list, and add the path above (or whatever is the location of your cl.exe).
