+========================================================================
+
+Support for User Defined macros and options has been added. The file
+UserMacros.cmake has an example of the technique. In the folder,
+config/cmake/UserMacros, is an implementation for Windows Visual Studio
+users for linking libraries to the static CRT - Windows_MT.cmake. 
+
+Copy the contents of the file, both macro and option, into the 
+UserMacros.cmake file. Then enable the option to the CMake configuration,
+build and test process.
