CMake build does not support HDF5

[MiCurry]

The CMake build currently does not support HDF5 usage. To do so we will need to:

• Specify -DHDF5 (add_compile_definitions(HDF5))
• Find the CMake Package: find_package(HDF5 ...) and link specific libraries:
  • hdf5::hdf55
  • hdf5::hdf5_fortran
  • hdf5::hdf5_hl
  • hdf5::hdf5_hl_fortran

We will also need to add the DataIO_HDF5.f90 instead of the DataIO.f90 to the ModEM exe's target sources.
