     Configuration:
     -------------
+    - Added support for MinGW + MSYS2 when building with CMake
+
+      We previously added support for this to the Autotools and the appropriate
+      configure-time checks have been added to CMake.

+      CMake + MinGW + MSYS2 is now tested with the following environments:
