Hi, wanted to take the project for a test spin :) Not really an expert with cmake, but I got this peculiar error when building ZeldaPython - not mentioning any particular src file

This seemed to work (open up the sln file and change the below mentioned property for ZeldaPython & ZeldaMeshlet): https://stackoverflow.com/questions/6626397/error-lnk2019-unresolved-external-symbol-winmain16-referenced-in-function#:~:text=Try%20to%20change,Console%20(/SUBSYSTEM%3ACONSOLE)

Try to change Properties -> Linker -> System -> SubSystem (in Visual Studio).

from Windows (/SUBSYSTEM:WINDOWS) to Console (/SUBSYSTEM:CONSOLE)
