FindHDF5: parallel HDF5 not detected with 3.26 but was with 3.25
On this project: https://github.com/PHAREHUB/PHARE the detection of the parallel HDF5 fails for the subproject HighFive with cmake 3.26, but works with 3.25 and former versions.
Commenting these lines
https://gitlab.kitware.com/cmake/cmake/-/blob/v3.26.0/Modules/FindHDF5.cmake#L226-228 introduced by !8015 (merged) make it work again.
more precisely if changing cmake_hdf5_test.cpp into cmake_hdf5_test.c
works
