This maintenance release improves life of Bazel users (no more "config.h" leaking into global include paths), fixes build with recent MinGW versions, and silences a number of static code analyzer and compiler warnings. The build targets exported by the CMake configuration of this library are now also prefixed by the package name "gflags::" following a more recent (unwritten) CMake convention. The unprefixed target names are still supported to avoid that dependent projects have to be modified due to this change in imported target names.
For a full list of changes, see the closed issues of v2.2.2 Milestone.
