I cannot overstate the importance of the initial contribution of this work made by Hiroshi Miura who brought most of the initial material. That said, without the sponsored maintenance program which helped polishing and making it production ready for all environments supported by GDAL, this would likely have remained a out-of-tree project. I believe most stakeholders (contributors and users, at least the ones who build from source) are very satisfied with this transition from the historic build systems to a unified and more modern one, with consistent option naming. Building on Windows is in particular much easier nowadays, in particular when leveraging dependencies from distributions like vcpkg or Conda Forge. For GDAL developers, the new build system offers integration with IDEs and solves long standing annoyances like missing header dependency rules for partial rebuilds.</span></p>

Given the number of environments tested and the number of dependencies of GDAL, there is hardly a week where some action is not needed in that area to make sure that the code builds and compiles cleanly, tests pass, etc. We can now track a few rolling distributions to detect as early as possible sources of incompatibilities with our dependencies, and act early: report issues to upstream if there are bugs, or do changes in our code & build scripts to take them into account.</span></p>
