Using R2016a in 64-bit Win7, and installed Microsoft Visual Studio 2015.
I was trying to install and compile MatConvNet library for CPU but I had some problem on compiling step. I follow the instructions in this website: http://www.vlfeat.org/matconvnet/install/
So the first step is Make sure that MATLAB is configure to use your compiler:
I tried "mex -setup" in command window and got MEX configured to use 'MinGW64 Compiler (C)' for C language compilation.
When I tried to conduct second step
> cd < MatConvNet >
> addpath matlab
> vl_compilenn
I got the error: 'cl.exe' is not recognized as an internal or external command, operable program or batch file.
Error using vl_compilenn>check_clpath (line 577) Unable to find cl.exe
Error in vl_compilenn (line 400) check_clpath(); % check whether cl.exe in path
Error in run (line 96) evalin('caller', [script ';']);
I have tried: add the path of visual studio cl.exe or copy the cl.exe file to MatConvNet download file
Anyone knows how to solve the problem?
Many thanks
Mei

I am using 2018a, windows 7 64 bit, student version. Installed Microsoft Visual 2017, MinGW-w64 5.3.0 at E:\mingw-w64\x86_64-5.3.0-win32-seh-rt_v4-rev0
I can set compiler to MinGW C++
>> mex -setup:C:\Users\user\AppData\Roaming\MathWorks\MATLAB\R2018a\mex_C++_win64.xml C++
I add cl.exe location (C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.12.25827\bin\Hostx64\x64) to my PATH I try to run vl_compilenn, the error message: (error-vl-compile.txt as attachment for more complete errors).
Please help to compile and setup vl. Thanks in advance.

If you look at the Supported Compiler chart https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/support/sysreq/files/SystemRequirements-Release2016a_SupportedCompilers.pdf you might notice that MingW is only supported for some kinds of compiling. And of course third-party toolboxes might have been coded in such a way that they do expect to use Visual Studio to compile.
The Community and Express versions of Visual Studios have not been supported compilers since around R2012a -- only the Professional (and probably Ultimate) versions have been supported.
As you have VS, you could try using mex -setup to configure VS. I am not convinced it will work, though: when I have seen the message about cl.exe before, it has typically had to do with a difference in executable name and configuration between the Professional and Express versions.

I had a similar problem with locating the cl.exe . What worked for me is in the Visual Studio tab in my start menu (using windows here) there is a command prompt tool called 'x64 Native Tools Command Prompt' . If you run commands or run the program from that shell it will somehow give access to that compiler.
I'm not sure why it works as I'm not knowledgable about c++ but I just need it to work for a project and it helped.

Note: in the years since I posted the above, support was largely added for non-professional editions of later VS compilers.
