Multiple Visual Studio installation and explicit toolset selection

If multiple Visual Studio versions are installed, and a toolset is explicitly request (-s option to phpsdk-starter.bat), only the latest Visual Studio is actually tried. E.g. for me I have Visual Studio 2019 and 2022, and have MSVC v141 installed only for Visual Studio 2019. Then doing phpsdk-starter.bat -c vc15 -a x64 -s 14.16 failed,

I think that is fixable by being more specific for vswhere -requires Microsoft.VisualStudio.Component.VC.Tools.x86.x64 (in my case vswhere -requires Microsoft.VisualStudio.Component.VC.v141.x86.x64 would do), but it doesn't seem worth the trouble. Might still be good idea to document, that you either need to have the exact Visual Studio version you want to build with installed, or that you need to install older toolsets for the latest Visual Studio you have installed.

Inizia con phpsdk-starter.bat e la relativa invocazione di vswhere, concentrandoti su come viene gestita la richiesta -s 14.16 quando sono installati Visual Studio 2019 e 2022. Determina se il toolset richiesto debba selezionare l’installazione corrispondente o se il requisito debba essere documentato. Il lavoro è completato quando il caso di toolset esplicito è gestito oppure i relativi requisiti di installazione sono documentati chiaramente.
