Not able to compile BCILAB on macOS 10.15.6 Catalina and MATLAB 2020a

[rajshekarreddy97]

I'm getting the following error although I have XCode and Xcode Command Line Tools installed.

Compiling the function/class arraydeal...failed.
Compiling the function/class cummax...failed.
All files in /Volumes/Reddy/Matlab Files/BCILAB-master/dependencies/mexutils-2013-11-11 failed to build; this indicates a problem in your build environment/settings.

In case you need to use a better / fully supported compiler, please have a look at:
http://www.google.com/search?q=matlab+supported+compilers+2020a

On Linux/UNIX, the best choice is usually a supported version of the GCC compiler suite.
Compiling the function/class .lbfgs...failed.
Please make sure that you have a supported compiler and that your build environment is set up correctly.
Also, please consider reporting this issue.

All files in /Volumes/Reddy/Matlab Files/BCILAB-master/dependencies/Scheduling-1.1 failed to build; this indicates a problem in your build environment/settings.
Please make sure that your system's java configuration matches the one used by MATLAB (see "ver" command).
There were compiling problems for the dependencies in:
/Volumes/Reddy/Matlab Files/BCILAB-master/dependencies/mexutils-2013-11-11
/Volumes/Reddy/Matlab Files/BCILAB-master/dependencies/liblbfgs-2011-12-19
/Volumes/Reddy/Matlab Files/BCILAB-master/dependencies/Scheduling-1.1

This means that the affected features of BCILAB will be disabled.
These issues are usually resolved by installing the Xcode application that comes with your OS (with all install options to include gcc compiler support).
Should BCILAB try to recompile in the future (or skip recompilation if not)? [y/n]
