rounds until everything is setup properly.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">Let's start with a Release build because that requires less tweaking. Go to "Project --> CMake Settings". Delete the default configuration ("x64-Debug (default)").<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">Add a new "x64-Release" configuration and set "Configuration type" to "Release". Save the CMakeSettings.json file, which will start a new CMake generation. "FIND_FLEX" will fail, so
you need to set the "FLEX_EXECUTABLE" path manually in section "CMake variables and cache". Browse to your win_flex.exe file. Additionally, disable "WITH_BINDINGS" and "WITH_QGIS_PROCESS". Save the file. Next set "BISON_EXECUTABLE" to your win_bison.exe file
and save again. Disable "WITH_QTWEBKIT" and save. Set "QCA_LIBRARY" to "<vcpkg-root>\installed\x64-windows\lib\qca.lib" and save. Configuration should now succeed, but you have to change "GEOS_LIBRARY" from "geos.lib" to "geos_c.lib". Save and start the build
after CMake generation has finished.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">Now let's do the same for a Debug build. Add a "x64-Debug" configuration and save. Change to the "x64-Debug" configuration in the toolbar. Repeat the steps from above (set flex and bison
paths etc.). When selecting libraries, take the libraries from "<vcpkg-root>\installed\x64-windows\debug\lib". Most libraries will have a "d" or "_d" as name suffix. The CMake generation will not always select the debug versions of libraries. Hence, go over
the CMake variables and change release library paths to debug library paths, e.g. "<vcpkg-root>\installed\x64-windows\debug\lib\geos_cd.lib" for GEOS_LIBRARY. I'll append my CMakeSettings.json file as reference to this mail. Save again and start the build.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">The build will fail because the execution of crssync.exe fails. That's because crssync.exe tries to load zstd.dll instead of zstdd.dll. I haven't figured out why, yet. An easy workaround
is copying zstdd.dll to zstd.dll in QGIS\out\build\x64-Debug\output\bin. Then restart the build and it should succeed.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">You should then be able to start and debug qgis.exe and its dependencies. Note that some vcpkg portfiles forget to copy over the .pdb files. For example, proj is affected. If you find
such a library with a missing .pdb file, check whether the portfile (e.g. "<vcpkg-root>\ports\proj4\portfile.cmake") contains the "vcpkg_copy_pdbs()" call. If not, just add it at the end, re-install the dependency and copy over the .pdb file to the QGIS output
directory.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="mso-fareast-language:EN-US">I'm currently trying to get QGIS working with Python bindings. I got the build working, however I'm struggling with the debug build execution. The debug Python library seems to be unable
to load the Release build Qt libraries that come with PyQt5. Well, I'll keep trying and if I succeed, I'll update the instructions.<o:p></o:p></span></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-US">Some time ago I discovered vcpkg (<a href="https://github.com/microsoft/vcpkg" target="_blank">https://github.com/microsoft/vcpkg</a>). vcpkg is a package manager
that downloads package source code to your local machine and builds the package locally. Recently, I discovered that vcpkg should be able to provide all dependencies to build at least the QGIS core application. Hence, I gave it a try.</span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-US"> </span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-US">Basically, it worked out of the box. I started with a fresh Windows 10 installation, installed Visual Studio 2019 Community Edition, Git, vcpkg, Python 3 and
flex and bison for Windows. I fetched all other dependencies via vcpkg. It was not necessary to even touch a single file in the repository. I could just open the main CMakeLists.txt file in Visual Studio and only had to tweak the CMake cache (the CMake find
macros that come with QGIS are not aware of vcpkg, so I had to set some paths manually). I had to switch off some extensions though as the required dependencies were not available via vcpkg (WITH_BINDINGS, WITH_QGIS_PROCESS, WITH_QTWEBKIT). The build did not
report any errors, I could start the application and it seems to work, but I did some light testing only.</span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-US"> </span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-US">I mainly tried it because I enjoy debugging with Visual Studio more than with gdb (or gdb wrapped in some IDE). In my experience, the performance of the Visual
Studio debugger is better and it is more stable, especially in long debug sessions.</span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-US"> </span><o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-US">I don’t want to promote official building support of QGIS with vcpkg. Providing the dependencies via OSGeo4W is much more reliable. However, if you don’t mind
the experimental nature of this setup and you want to be able to debug into QGIS’ dependencies, you might give it a try. Especially, if you want to track the cause of a crash in one of QGIS’ dependencies, this setup might be helpful. You have the source code
and debug versions of the dependencies, so the debugger will jump to the crashing code line and you can inspect all the variables of the dependency.</span><o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-US">If someone is interested in trying it, give me a note. I can then assemble detailed instructions on how to make it work. It took me a while to figure out which
packages are needed and how the CMake cache needs to be tweaked.</span><o:p></o:p></p>
