I use CMake 4.3.3 (no custom settings).
I had CMake 4.3.2 a month ago when I submitted the CMake minimum version
required change to trunk, to avoid that hard error (and was hitting the
same error locally:
Unexpected enablement value "i" for mod_authnz_ldap.
....that was also shown in the CI for branch 2.4.x
At that time, I chose not to submit the 'unset' workaround, even though
it popped back up here in the CI runs again.

See this: https://github.com/jajik/httpd/actions/runs/26829154521/
<https://github.com/jajik/httpd/actions/runs/26829154521/>. It's
2.4.x running with VS 2022.*
Is it possible you have a CMake setting that treats warnings as errors?
(like https://cmake.org/cmake/help/latest/variable/
CMAKE_ERROR_DEPRECATED.html <https://cmake.org/cmake/help/latest/
variable/CMAKE_ERROR_DEPRECATED.html>) Which version of CMake do you
have? We might be missing something else...
Best,
Vlad
* The reason it works without the trunk fix is that in my fork `windows-
latest` is still the old container with VS 2022 while apache/httpd was
already moved to the new image with VS 2026.

Joe seemed stressed about needing a workaround to get that branch 2.4.x
running, and I provided the workaround.
I actually agree not to commit the 'unset(i)', notice that I submitted
the CMAKE_MINIMUM_REQUIRED change a month ago to trunk, as I figured
that my unset(i) change was not optimal. (however, to this day, I need
that unset(i) to get branch 2.4.x to compile, as mentioned by Joe in
his
GitHub run).
/me just trying to help
