* CMake: (fix) Changed names of the resulting config files. Changed the name LibaecTargets.cmake, LibaecConfig.cmake and LibaecConfigVersion.cmake to libaecTargets.cmake, libaecConfig.cmake and libaecConfigVersion.cmake such that these files can be found by cmake on a Linux machine. * CMake: (feature) Better integration with HDF5. - Changed the build such that always a static and shared library with be built. - Rewritten CMake config files such that - One can select the shared or static library. - Set several libaec variables such one can, for example, check if the libaec library is found. - Set several Szip variables for the same reason as for setting the libaec variables. This is useful for a better integration with HDF5 when building HDF5 from scratch.
