Stéphane,
Hello!
I'm glad to see another platform using the CMake build for HDF5,
however, please understand that the CMake project started for the Windows
platform and we have had limited usage on other platforms. Please visit our
CDash site (http://cdash.hdfgroup.uiuc.edu) for known submissiions.
As for your issues, yes we have not implemented the wrapper scripts. This is
because of the previous mentioned start on the Windows platform, and our
reliance on the community to provide CMake coding for other platforms.
The size difference might be attributted to the use of --enable-trace for the
autotools/configure build and not enabling it in the CMake options?
Finally, we have not had anyone try OpemMPI with CMake - just mpich2.
I am willing to provide help in improving this configuration of CMake-built
HDF5 and with your cooperation we could add another platform to our list.
