[CMake] FindHDF5.cmake and the "hl" versions of hdf5 libs

[Michael Jackson]

I guess what would be nice is that the FindHDF5.cmake file can take  
components like "C", "C++" "HL", "Fortran" instead of hard coding them  
into the FindHDF5.cmake file.

Will, As maintainer of the hdf5 find module can you make this happen  
before the next release of CMake?
