Upstream nightly CI failing

[lilyminium]

Update for Copilot:

This action is failing. Diagnose and fix the issue. The workflow is in https://github.com/openforcefield/openff-nagl/blob/dfc8102889b93b34582535fcee20932e4d2df7de/.github/workflows/dev-ci.yaml .

Something to do with installing and importing DGL.

Ubuntu test has:

 CMake Error at third_party/dmlc-core/CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

cmake is v4 though.

@mikemhenry same thing as we're seeing in OpenMM world?

It took me a bit of time to understand what is going on in this but it looks like you are building DGL from source but don't check out a tag, so this is very likely to break as things change. I bet if you add a which -a cmake command to the CI, you will find more than bin and my hunch is that either the cmake call here https://github.com/openforcefield/openff-nagl/actions/runs/16699216710/workflow#L63 is pointing to the wrong cmake OR one of the source files has a hard coded path to /usr/bin/cmake or something which is why we are seeing this error

Taking the liberty to change the name of this issue to clarify that it's "only" the nightly CI that builds from upstreams' source and nightly CI installing from released versions is fine
