Matlab Compiler fails to include enum class with no methods

I'm trying to compile matlab 2017a code. When I run the compiled code I get the following runtime error:

Standard exception: *.cpp:line# -- Undefined variable "EnumClass" or class "EnumClass.enum1".

The enum class is defined according to https://www.mathworks.com/help/matlab/matlab_oop/enumerations.html. Roughly:

classdef EnumClass
    enumeration
        enum1, enum2, enum3
    end
end

I suspect this is because the Matlab Compiler fails to detect EnumClass as a dependency because the matlab compiler detects dependencies using only functions https://www.mathworks.com/matlabcentral/answers/323654-compiler-and-missing-source-files. The enum class has no functions to call.

I know that I can manually specify dependencies with the mcc -a flag, but this is not very maintainable for my situation. There are multiple separate teams each working on modules that get compiled in a programmatic way. So manually specifying dependencies creates undesirable complexity in this process.

Is there a way to change EnumClass or its caller to cue the Matlab Compiler that EnumClass is a dependency?

Enumeration class can be also included in a standalone application by MATLAB Compiler without specifying the dependency. I have confirmed in R2019b Update 3 that the following command creates a standalone application properly.

mcc -m callEnumTest.m

callEnumTest.m

function callEnumTest
    thisDay = WeekDays.Tuesday;
    disp(thisDay)
end

WeekDays.m

classdef WeekDays
   enumeration
      Monday, Tuesday, Wednesday, Thursday, Friday
   end
end

I also confimed that Application Compiler app can add dependent files (WeekDays.m) properly.

Anyway, you can add dependencies manually by adding "-a" option in mcc command. For example,

mcc -m callEnumTest.m -a WeekDays.m

Thank you for your prompt response. I think I failed to mention some details. I have updated my question. Any additional information would be greatly appreciated.
