[texworks] [XeTeX] Alternative location for output PDF files (and, ideally, all non-source files)

If an output directory is defined by a user, the TeX library
first searches for files to read in the output directory.
Therefore files such as foo.aux should be read successfully
with the default TEXINPUTS.xetex etc.
In fact, it is working like this here.
Please try once more with the default TEXINPUTS.xetex.

Best,
Akira
