Add sunset message to CMakeList.txt file 

The commit also attempts to avoid the shell command for Windows machines.
If no one has patches to offer for the outstanding CMake bugs, then this is the version that will be moved to the Wiki Patch Page. The community will have to tend to the outstanding bugs when someone with domain experience can work them

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\
community maintained CmakeList.txt at http://www.cryptopp.com/wiki/CMake.\n\
