<p class="MsoNormal"><span lang="EN-US">AFAIK, QGIS has only recently be bumped to C++17, and the version of spatialindex in vcpkg is still 1.9.0. The fix for the binary_function issue made it to a later version only. So,
the bad news is that the build with vcpkg is broken for now.<u></u><u></u></span></p>
<p class="MsoNormal"><span lang="EN-US"><u></u> <u></u></span></p>
<p class="MsoNormal"><span lang="EN-US">I’ve read Mathias Kuhn’s mail, and his idea of having a curated vcpkg fork seems the best approach to me to solve these kind of issues. On the one hand, we can prevent changes in upstream
from breaking the build. On the other hand, we can update dependencies on our own (like the spatialindex library), merge it to the fork and then open a pull request to upstream. We would not be blocked by the upstream review process that way.<u></u><u></u></span></p>

We have now a new tab on github called 'discussions'[1]. Your detailed<br>
instructions are a good candidate to write down a new entry there, under<br>
'Show and tell' category. The goal is to keep this information next to<br>
the repo. You can use the markdown syntax to enhance the writing format.<br>
You can also add some print screens.<br>

This is just a suggestion. Feel free to put it there or not.<br>
