+	For PackageReference library projects where buildTransitive is supported we'll default to setting CefSharpAnyCpuSupport to true
+	This should only require WinExe and Exe projects to specify CefSharpAnyCpuSupport rather than every project in a solution.
+	Only for PackageReference projects where NuGetToolVersion > 5.0 and OutputType is library.
+	Defaulting CefSharpAnyCpuSupport to true is simpler than modifying the already complex Condition for the CefSharpPlatformCheck
+	target below.
