From 195d47e2139171cbae18a7164daac1f59be54ebe Mon Sep 17 00:00:00 2001
From: Brad King <brad.king@kitware.com>

Subject: VS: Allow CMAKE_GENERATOR_INSTANCE to specify portable instance
Previously the `CMAKE_GENERATOR_INSTANCE` value was used only to filter
the instances reported by the Visual Studio Installer tool. If the
specified install location is not known to the VS Installer, but the
user provided a `version=` field, check for the installation directly
on disk.
Fixes: #21639, #22197
