ERROR: LoadError: UndefVarError: `libhdf5` not defined in Julia 1.10 DEV

When I tried to install HDF5 master in Julia 1.10 DEV, I get the following error:

I tested this on x86-64 Linux and HDF5 master branch seems load normally there.

Every so often this exact error comes up for me and it takes a lot of messing around until it just seems to go away. Is there maybe a better way to handle this libhdf5 variable so this doesn't happen anymore? It seems like it's just being spawned out of thin air (it's not defined in the code) and I can't tell what conditions make it appear or not.

I think the issue is probably due to an old HDF5_jll being installed. Check the HDF5_jll version.
