conda-forge missing Windows Packages

[WillAyd]

Got this error when trying to install the windows adbc packages in pandas CI:

   error    libmamba Could not solve for environment specs
      The following packages are incompatible
      ├─ adbc-driver-postgresql >=0.7.0  is not installable because it requires
      │  └─ adbc-driver-manager >=0.7.0,<1.0a0 , which does not exist (perhaps a missing channel);
      └─ adbc-driver-sqlite >=0.7.0  is not installable because it requires
         └─ adbc-driver-manager >=0.7.0,<1.0a0 , which does not exist (perhaps a missing channel).

We've punted on Windows on conda-forge so far because we couldn't resolve build issues, it may be time to fix that

Let's see how this goes: conda-forge/arrow-adbc-split-feedstock#17

[lidavidm]

Ah, so we need to trick CMake into using gcc for the go build and cl for everything else...

This came up in OSGeo/gdal#11003 (comment) (GDAL wants to use the conda driver manager but can't on Windows because packaging is diabled:

I can see about trying this again...I think we "just" need to force Go-on-Windows to use gcc and not MSVC

[paleolimbot]

Or we could skip the Go drivers for the first attempt? The missing driver manager is the part that was causing some uncertainty/doubt as to whether ADBC worked on Windows.

[lidavidm]

Hmm, that should work.
