How to get Matlab C++ compiler name in my program?

I am developing a C++ application and I need to get the C/C++ compiler name of Matlab (2017b and newer). I have already tried using Matlab Engine C++ API for launching an engine and then running:

mex -setup C++

But this approach is taking a long time to be completed. Is there any better approach to get the C/C++ compiler name of Matlab without launching a Matlab instance (e.g. reading a configuration file, etc.)?

If starting Matlab is fine, then this code will get you all the info you need:

details=get_cpp_compiler_info

details = 
  CompilerConfiguration with properties:

             Name: 'g++'
     Manufacturer: 'GNU'
         Language: 'C++'
          Version: '8.3.0'
         Location: '/usr/bin/g++'
        ShortName: 'g++'
         Priority: 'A'
          Details: [1×1 mex.CompilerConfigurationDetails]
       LinkerName: '/usr/bin/g++'
    LinkerVersion: ''
           MexOpt: '/MATLAB/bin/glnxa64/mexopts/g++_glnxa64.xml'

function details=get_cpp_compiler_info
cc=mex.getCompilerConfigurations;
for details=cc(:).'
    if strcmp(details.Language,'C++'),return,end
end
error('C++ compiler not found')
end

If that is not an option, you could try reading the xml file in the prefdir:

fn=sprintf('%s%smex_C++_%s.xml',prefdir,filesep,mexext)

fn = '/tmp/matlabpref/mex_C++_mexa64.xml'

Although you should be aware that I could only find this file on Windows.
