Trim whitespace when parsing <TraverseFiles> contents?

[MarijnS95]

For Tsukisoft/direct-storage-rs#5

We had a list of the form:

            <TraverseFiles>
                $(PkgMicrosoft_Direct3D_DirectStorage)\native\include\dstorage.h;
                $(PkgMicrosoft_Direct3D_DirectStorage)\native\include\dstorageerr.h
            </TraverseFiles>

But no constants from dstorageerr.h were parsed. Swapping the filenames makes it so that #defines from dstorage.h are lost, but defines from dstorageerr.h are parsed.

I believe the raw string it's parsing here is: dstorage.h;\ndstorageerr.h\n, splitting this on ; causes the last filename to never match. Perhaps a string item = items[i].Trim(); is missing here to make multiline filename strings work more naturally?

win32metadata/sources/GeneratorSdk/MetadataTasks/ScrapeHeaders.cs

Lines 476 to 488 in 3d2ba1e

	private string[] GetFilesFromMetadata(ITaskItem item, string name)
	{
	string[] items = item.GetMetadata(name).Split(';', System.StringSplitOptions.RemoveEmptyEntries);
	for (int i = 0; i < items.Length; i++)
	{
	if (!Path.IsPathRooted(items[i]))
	{
	items[i] = Path.Combine(this.MSBuildProjectDirectory, items[i]);
	}
	}
	return items;
	}

After all, when merging this into one line:

            <TraverseFiles>$(PkgMicrosoft_Direct3D_DirectStorage)\native\include\dstorage.h;$(PkgMicrosoft_Direct3D_DirectStorage)\native\include\dstorageerr.h</TraverseFiles>

Both files were finally parsed correctly.
