Thank you for your reply. What I am wanting to do is build CGNS ( https://cgns.github.io/WhatIsCGNS.html) in parallel to get parallel I/O, which requires HDF5 to be built in parallel - its not just thread safety I am after.
Everything works fine on Linux, since there I can still use configure to build HDF5 and even Intel give advice on how to build it with their compilers at https://software.intel.com/en-us/articles/performance-tools-for-software-developers-building-hdf5-with-intel-compilers . The problem is that the move to cmake has left me in the dark now. If configure was still supported on Windows for HDF5, then I the path forward is known. cmake appears to be very VS centric, which is fine if you are OK with MS compilers and not clear to me how I can switch to Intel compilers.
