Mex Error Related to jl_options = JL_OPTIONS_HANDLE_SIGNALS_OFF on Julia 1.6.2

[GrantHecht]

I've been playing around with trying to call Julia from MATLAB with Julia v1.6.2 on Windows using the Microsoft Visual C++ 2019 compiler and started running to the mex error:

Error using mex
   Creating library C:\Users\granthec\.julia\dev\Mex.jl\mexjulia\mexjulia.lib and object
   C:\Users\granthec\.julia\dev\Mex.jl\mexjulia\mexjulia.exp
mexjulia.obj : error LNK2019: unresolved external symbol __imp_jl_options referenced in function mexFunction
C:\Users\granthec\.julia\dev\Mex.jl\mexjulia\mexjulia.mexw64 : fatal error LNK1120: 1 unresolved externals

I was eventually able to compile the mex function successfully editing mexjulia.cpp to either:

//jl_options.handle_signals = JL_OPTIONS_HANDLE_SIGNALS_OFF;

or

//jl_options.handle_signals = JL_OPTIONS_HANDLE_SIGNALS_OFF;
jl_options_t jl_options;
jl_options.handle_signals = JL_OPTIONS_HANDLE_SIGNALS_OFF;

I'm not super familiar with C++ and assume both of these options likely will result in undesirable behavior but I wanted to document the error I was running into and the quick fix that I used.
