[QGIS-Developer] How to build qgis on Windows 10

[Deimer Caldera]

Hi, thank you for your quick answer.



I have checked and the package Qwt is installed, so do you have any other idea?

QwtPlotCurve sounds like you are missing QWT? This is documented
      in the up-to-date documentation at https://github.com/qgis/QGIS/blob/master/INSTALL.md#2-overview and
      has been written in that document for at least two years.

I have tried to build qgis from source with this document https://github.com/qgis/QGIS/blob/ltr-3_22/INSTALL.md but
          I got many errors. Recently I found this guide

https://www.mail-archive.com/qgis-developer@lists.osgeo.org/msg52306.html but
          the build gives me some errors (error LNK2019: unresolved
          external symbol).

            : fatal error LNK1120: 2 unresolved externals



Am I missing a package to install?


Is there any updated documentation to make the build
              successful?



Thank you so much for your attention.
