clickable includegraphics for cross reference data

Question

I’d like to make references work in my robust-externalize library. I wanted to parse the aux file, extract the lines related to a label like:

\newlabel{sec:dependencies}{{3.4}{7}{Dependencies}{subsection.3.4}{}}
\newlabel{sec:dependencies@cref}{{[subsection][4][3]3.4}{[1][7][]7}}

and input this in the preamble of my document. As a proof of concept, I wrote:

\begin{CacheMe}{latex, add to preamble={\usepackage{hyperref}\newlabel{sec:dependencies}{{3.4}{7}{Dependencies}{subsection.3.4}{}}}}
  Hello \ref{sec:dependencies}.
\end{CacheMe}

and it kind of work!

But there is an annoying issue: I cannot click the link to go to the appropriate section (while writing \ref{sec:dependencies} anywhere in the document would work). Do you know if there is a way to make \includegraphics work for links as well?

MWE:

\documentclass{article}
\usepackage{robust-externalize} % You certainly need to download the .sty in github.com/leo-colisson/robust-externalize, and compile with -shell-escape, or manually (see doc)
\usepackage{hyperref}
\begin{document}
\section{Dependencies}\label{sec:dependencies}
\begin{CacheMe}{latex, add to preamble={\usepackage{hyperref}\newlabel{sec:dependencies}{{1}{1}{Dependencies}{section.1}{}}}}
  Hello, go to section \ref{sec:dependencies}.
\end{CacheMe}
\end{document}

EDIT

I tried with newpax but it is not working, the link points to the included image itself. I think that the problem is that when I compile the subfile with pdflatex robExt-471D7E5B93E3AC81760E014C437DDD7B.tex, that actually contains:

\documentclass[,margin=0cm]{standalone}
 \usepackage {hyperref}\newlabel {sec:dependencies}{{2}{2}{Dependencies}{section.2}{}}
\begin{document}%
%% We save the height/depth of the content by using a savebox:
\newwrite\writeRobExt%
\immediate\openout\writeRobExt=\jobname-out.tex%
%
\newsavebox\boxRobExt%
\savebox{\boxRobExt}{%
  Hello, go to section \ref {sec:dependencies}.%
}%
\usebox{\boxRobExt}%
\immediate\write\writeRobExt{%
  \string\def\string\robExtWidth{\the\wd\boxRobExt}%
  \string\def\string\robExtHeight{\the\ht\boxRobExt}%
  \string\def\string\robExtDepth{\the\dp\boxRobExt}%
}%
%
\end{document}

I get a warning:

pdfTeX warning (dest): name{section.2} has been referenced but does not exist, 
replaced by a fixed one

So I guess that the question can be reformulated as "how to make latex keep the link even if it is not present in the current document".

Here is the paxfile as well:

\[{pax}{0.1l}\\
\[{file}{(./robExt-471D7E5B93E3AC81760E014C437DDD7B.pdf)}{
  Size={13783},
  Date={D:20230906164541+02'00'},
}\\
\[{pagenum}{1}\\
\[{page}{1}{0.0 0.0 94.977 8.856}{}\\
\[{annot}{1}{Link}{86.232 -0.996 93.206 9.852}{GoTo}{
  C={[1 0 0 ]},
  H={/I},
  Border={[0 0 1 ]},
  DestLabel={1},
}\\
\[{dest}{1}{1}{Fit}{
}\\

But for reference, here is the full procedure, without shell escape:

1. create

\DocumentMetadata{uncompress}
\documentclass{article}
\usepackage{pdfpages,xcolor}
\usepackage{robust-externalize} % You certainly need to download the .sty in github.com/leo-colisson/robust-externalize, and compile with `-shell-escape`, or manually (see doc)
\usepackage{hyperref}
\usepackage{newpax}
\newpaxsetup{usefileattributes=true}
\begin{document}
\section{Test}
\newpage
\robExtConfigure{latex/.append style={do not add margins}, enable manual mode}
\section{Dependencies}\label{sec:dependencies}
\newpage
\section{Test}
\robExtConfigure{latex/.append style={do not add margins}}
\begin{CacheMe}{latex, name output=mycompiledfile, add to preamble={\usepackage{hyperref}\newlabel{sec:dependencies}{{3}{3}{Test}{section.3}{}}}}
  Hello, go to section \ref{sec:dependencies}.
\end{CacheMe}
\mycompiledfile
%%% Uncomment later:
%\includegraphics{\mycompiledfile.pdf}
\ref{sec:dependencies}
\end{document}

2. compile with:

mkdir robustExternalize
pdflatex debug-crossref.tex
# look in debug-crossref-robExt-compile-missing-figures.sh, but it should be:
cd robustExternalize/ && pdflatex -halt-on-error "robExt-471D7E5B93E3AC81760E014C437DDD7B.tex" && cd ..

3. copy the robExt-471D7E5B93E3AC81760E014C437DDD7B.pdf file in the main folder (don't know how to make it work in subfolder):

cp robustExternalize/robExt-471D7E5B93E3AC81760E014C437DDD7B.pdf .

4. Create a file testnewpax.tex with:

\documentclass{article}
% load the lua code
\directlua{require("newpax")}
% write .newpax files for newpax.sty
\directlua
{
newpax.writenewpax("robExt-471D7E5B93E3AC81760E014C437DDD7B")
}
\begin{document}
\end{document}

compile that file with lualatex:

lualatex testnewpax.tex

Uncomment the line after Uncomment later in the above document, and recompile it twice:

pdflatex debug-crossref.tex
pdflatex debug-crossref.tex

See that the created link does not point to the right section.
