Merging in latest from upstream (HDFFV/hdf5:refs/heads/develop)

* commit 'dcc66a4f157ace0858b788228550f3e104df3242': (35 commits) GGC requires attribute before function Correct COMPILE defs usage Add missing module_dir property Text cleanup Correct sentence punctuation. Add release note. Use set_property for MT flag Correct command usage Remove APPEND Fix typo Add missing test lib add missing folder to path Fix another command revert Missed a command revert Revert to old style for LINK_FLAGS gen expr not working LINK_FLAGS must be separate property sets Fix link flags syntax Revert refactor link flags refactor link flags to interface Refactor link flags ...

+    - Converted CMake global commands ADD_DEFINITIONS and INCLUDE_DIRECTORIES
+      to use target_* type commands. This change modernizes the CMake usage
+      in the HDF5 library.
+
+      In addition, there is the intention to convert to generator expressions,
+      where possible. The exception is Fortran FLAGS on Windows Visual Studio.
+      The HDF macros TARGET_C_PROPERTIES and TARGET_FORTRAN_PROPERTIES have
+      been removed with this change in usage.
+
+      The additional language (C++ and Fortran) checks have also been localized
+      to only be checked when that language is enabled.
