-Starting with netCDF-C 4.3.0, we are happy to announce the inclusion of CMake support.  CMake will allow for building netCDF on a wider range of platforms, include Microsoft Windows with Visual Studio.  CMake support also provides robust unit and regression testing tools.

+## Setting the HDF5 Plugin Path
+
+Use the --with-plugin-dir= option to set the HDF5 plugin path. This
+path must contain the directory where HDF5 filters have been
+installed. --with-plugin-dir accepts three values:
+
+* yes - use the first directory in environment variable
+HDF5_PLUGIN_PATH (if it is set), or /usr/local/hdf5/lib/plugin (Unix)
