Poor error message from IL2CPP on Windows Desktop with specific Visual Studio installation sequence
I'm submitting this bug report on behalf of a user who posted about it on the forum here: https://forum.unity.com/threads/il2cpp-build-problem.994606/#post-6458698
I've not reproduced it locally, but it seems these are the Visual Studio installation steps, as described by the user:
- had VS2017, uninstalled it
 - installed VS2019
 - added some .NET versions
 - added Unity Hub
 
Then when the user builds an IL2CPP player, they get a rather cryptic error message from the Microsoft C++ compiler:
Cannot open include file: 'string.h': No such file or directory
Likely, the issue is that the C++ workload for Visual Studio is not installed. However, Unity or IL2CPP should be able to detect this case and provide a better error message.
