Why is MATLAB R2018b not using the compiler that I selected for a COM component?

I have VS2013 and VS2015 installed. I am trying to compile a deployed application (COM Server) using mcc. It uses VS2015. When I compile, I get an internal compiler error:

cl /c /GR /W3 /EHsc- /nologo /MT /O2 /Oy- /DNDEBUG /DMATLAB_DEFAULT_RELEASE=R2017b /DUSE_MEX_CMD /DMSVC /DIBMPC /D_CRT_SECURE_NO_DEPRECATE /D_SECURE_SCL=0 -I"mcr_solver" -I"C:\Apps\matlab95\extern\include" -I"C:\Apps\matlab95\simulink\include" -I"mcr_solver" -I"C:\Apps\matlab95\extern\include\win64" -I"C:\Apps\matlab95\extern\include" -I"mcr_solver" "H:\Projects\SRA\SRA\mcr_solver\Solver_com.cpp" /FoC:\Users\<username>\AppData\Local\Temp\mex_314603302956460_14840\Solver_com.obj

Error: An error occurred while shelling out to mbuild (error code = -1).

Unable to build executable.

 

I tried forcing MBUILD to use VS2013 like this:

>> mex -setup:C:\Users\<username>\AppData\Roaming\MathWorks\MATLAB\R2018b\MBUILD_C_win64.xml C -client MBUILD

However, it still uses VS2015 in the compile process. How do I get it to use VS2013?

Because a COM component is being compiled, "mbuild" compiler needs to be configured. To do this, use the following to set up your your "mbuild" compiler rather than "mex -setup":

>> mbuild -setup -client mbuild_com
