+MESSAGE( STATUS
+"*************************************************************************\n\
+CMake support is being sunsetted. It is a redundant build system because\n\
+the Makefile is used on Unix & Linux; and Visual Studio & MSBuild are used\n\
+on Windows. Lack of Native CMake support for AIX, Android, iOS, PowerPC,\n\
+Solaris, Windows Phone, Windows Store, SSE, ARMv7, ARMv8 and Power8 placed\n\
+too much of a burden on the library maintainers. You can find the latest\n\
