texdepends gets the test for the graphic existence wrong for xetex,
it assumes that the graphic is not there and set its size to 1pt
which then confuses pdfpages. It also gives errors if you set the
width of a graphic. This here could work (but I'm not sure that it
covers all cases):

\RequirePackage{texdepends}
\makeatletter
%
\def\TD at Gread@pdf#1{%
  \IfFileExists{\ifxetex \Gin at base\Gin at ext \else #1\fi}{% changed
    %\PackageWarning{texdepends}{Gread File '#1' exists}%
    \TD at orig@Gread at pdf{#1}%
  }{%
    \PackageWarning{texdepends}{No '#1' file \MessageBreak
      using 1 for graphic dimensions}%
    \setbox\@tempboxa\hbox{\relax}%
    \def\Gin at llx{1}\let\Gin at lly\Gin at llx
    \Gin at defaultbp\Gin at urx{\wd\@tempboxa}%
    \Gin at defaultbp\Gin at ury{\ht\@tempboxa}%
  }%
}%

\makeatother
\documentclass{article}

\usepackage{graphicx,pdfpages}

\begin{document}

\includegraphics[width=5cm]{example-image.pdf}

\includepdf{example-image}

\end{document}
