Configuration:
-------------
+ - On macOS, Universal Binaries can now be built, allowing native execution on
+ both Intel and Apple Silicon (ARM) based Macs.
+
+ To do so, set CMAKE_OSX_ARCHITECTURES="x86_64;arm64"
+
+ (SAM - 2021/02/07, https://github.com/HDFGroup/hdf5/issues/311)

- Added a configure-time option to control certain compiler warnings
