     Configuration
     -------------
-    -
+    - Move MPI libraries link from PRIVATE to PUBLIC
+
+      The install dependencies were not including the need for MPI libraries when
+      an application or library was built with the C library. Also updated the
+      CMake target link command to use the newer style MPI::MPI_C link variable.
