Support /external includes

[ssproessig]

We use the /external feature to mark any include in brackets as external, so that we can use /W4 for our code, but /W0 for external.

Option enabled with

    /W4 /experimental:external /external:anglebrackets /external:W0

Unfortunately the extension seems not to support this, as the includes for Qt are not taken over

Visual Studio stores them under "Additional Options"

Thanks for letting me know. I have never used this feature to be honest. I will run some tests and see if I can retrieve that info from the extension.

What version of the extension are you running on? I made some changes on v0.7.1 so that even if the build fails it will still return a struct in case that build error was not related with the layout.

I'm running the latest version of the addin - and can confirm, that it works, as long as the struct is not using any Qt types
