ADIOS 2.11.0 DILL CMake issue on macOS GH Action Runners

[ax3l]

In openPMD/openPMD-api#1833, I am trying to build an all-static build of openPMD-api dependencies, including ADIOS2.
I am updating that build logic from ADIOS 2.10 to 2.11 right now.

My Linux builds are all good. Using the exact same build logic, but on macOS-14 arm64 and macOS-15 x86_64 GitHub runners alike, I get the following error from just updating from 2.10 to 2.11:

The exact build logic is in the above link in the file library_builders.sh

attn @eisenhauer @pnorbert @vicentebolea please help :)

Hey @ax3l ! Lots of CMake logic changed here, trying to make dill optional where it wasn't available. Not sure why it's going badly in this situation yet, but I'll dig into it on monday.

Thanks, Greg! Let me know if my build options are weird or something, hope it's easy to spot :)
