[BUG]: Cmake variable change - HDF5_PROVIDES_PARALLEL #4035
Description
Summarize the issue
I am having a build issue with the current v0.10.post5 where HDF5 is detected but mistakenly identified as a serial package, despite MPI features working. After some debugging, I discovered that some minimal modifications to include additional variable checks in the cmakelists files works.
Upstream, the HDF5 group changed the cmake variable names causing build failures with the recently released HDF5 v2. In the CmakeLists.txt build definitions, HDF5_IS_PARALLEL has been renamed:
What this means is if you have in your CMake build a check, for example, if (NOT (HDF5_IS_PARALLEL OR HDF5_ENABLE_PARALLEL)), you would want to add if (NOT (HDF5_IS_PARALLEL OR HDF5_ENABLE_PARALLEL OR HDF5_PROVIDES_PARALLEL))
How to reproduce the bug
Build fails on arch linux with hdf5-openmpi:
Found HDF5 at /usr/lib/cmake/hdf5 via NO_MODULE. Now trying to extract locations etc.
