CI: add HDF5 2.0.0 to test matrix

[captainkirk99]

Summary

The CI matrix for both Ubuntu and macOS does not test against HDF5 2.0.0. This should be added to ensure netCDF-C remains compatible with the latest major HDF5 release.

What was done

HDF5 2.0.0 has been added to the following CI jobs in run_tests_ubuntu.yml and run_tests_osx.yml:

Build dependency jobs

• build-deps-serial (Ubuntu): matrix extended to [1.10.8, 1.12.2, 1.14.3, 2.0.0]
• build-deps-osx (macOS): matrix extended to [1.12.2, 1.14.3, 2.0.0]

The build step required a special case for 2.0.0 because HDF5 2.0.0 is CMake-only — it no longer ships an autotools ./configure script, and the source tarball is only available from GitHub (not the HDF FTP server):

# Download
wget https://github.com/HDFGroup/hdf5/archive/refs/tags/hdf5_2.0.0.tar.gz
tar -zxf hdf5_2.0.0.tar.gz
mv hdf5-hdf5_2.0.0 hdf5-2.0.0   # GitHub archives extract as hdf5-hdf5_2.0.0/

# Build with CMake
cmake -S hdf5-2.0.0 -B hdf5-2.0.0/build \
  -DCMAKE_INSTALL_PREFIX=${HOME}/environments/2.0.0 \
  -DHDF5_BUILD_HL_LIB=ON \
  -DHDF5_BUILD_SHARED_LIBS=ON \
  -DHDF5_BUILD_STATIC_LIBS=OFF \
  -DCMAKE_BUILD_TYPE=Release
cmake --build hdf5-2.0.0/build -j
cmake --install hdf5-2.0.0/build

CMake test jobs (both Ubuntu and macOS)

• nc-cmake / nc-cmake-osx: added 2.0.0 with exclude: hdf5: 2.0.0 / use_nc4: nc3 (nc3 disables HDF5 so those combinations are meaningless)
• nc-cmake-tests-oneoff-osx-shared: added 2.0.0
• nc-cmake-tests-oneoff-osx-static: added 2.0.0

Autotools test jobs

The nc-autotools (Ubuntu) and nc-autotools-osx / nc-ac-tests-oneoff-osx (macOS) jobs were not given 2.0.0 in the full matrix for the autotools-based netCDF configure (the Ubuntu nc-autotools job does include it since HDF5 2.0.0 still installs pkgconfig and shared libs that ./configure --enable-hdf5 can find via CFLAGS/LDFLAGS).

Notes

• The verified GitHub tarball extraction directory name is hdf5-hdf5_2.0.0/ (confirmed via tar -tzf).
• HDF5 2.0.0 is available locally at /usr/local/hdf5-2.0.0 on the dev machine.
• No changes were needed to the Windows or big-endian CI workflows.

Please bump this to the current release, HDF5 2.1.0. Thanks.

Hmmm. Make that HDF5-2.1.1, bugfix release, coming any moment now. The release files are already published.
