Mex problems with Visual Studio 2017 Community Edition

Dear Matlab community,

I am experimenting with MatConvNet on Windows 10 64-bit with Visual Studio 2017 Community Edition installed. After noticing cl.exe was missing I installed the necessary components through modification of VS Installer. Now I have C/C++ compiler of VS and added it to the system path. However, I had MinGW64 Compilers installed before this and now I cannot switch the compiler in mex to that one through the following command.

>> mex -setup:'C:\Program Files\MATLAB\R2018b\bin\win64\mexopts\msvcpp2017.xml' C++

Error using mex

MEX cannot use compiler 'Microsoft Visual C++ 2017' because that

compiler is not found.

Although I installed the C/C++ compiler it cannot be selected through the command I quoted above. What might be the reason and how this issue can be solved?
