If we did our job correctly, you should not have to make any changes to 
your current CMakeLists.txt files. And yes, having a CMake build system 
alleviates a lot of pain of building HDF5 on certain platforms and for 
"Clients" who are using CMake and want to build HDF5 as a part of their 
project.

If you do try it and come across any issues, please let me know or post 
them on the HDF email list.

Thanks
