Build error in GPU coder - nvcc fatal: Cannot find compiler 'cl.exe' in PATH

I'd like to create a MEX function from my MATLAB function that has an gpuArray input. I used the GPU Coder but I got an error when I tried to build a MEX file:

I checked the Build Log and it says the following:

nvcc fatal : Cannot find compiler 'cl.exe' in PATH

It seeems like that cl.exe is the Visual C++ compiler. One directory this execuatable is located is

C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\14.29.30133\bin\Hostx64\x86

so I added this directory to the system path as well as to the MATLAB search path:

However, even after this, I still got the same error.

Does anyone have an idea how to fix this problem?

I fixed this problem by simply restarting MATLAB. Thank you.
