 To use CMake, create CMakeLists.txt in each directory that makes up your

+ADDING COMMANDS
+---------------
+Rules can be added to CMake by deriving new commands from the class cmCommand 
+(defined in CMake/Source/cmCommand.h/.cxx).

+
+ADDING MAKEFILE SUPPORT
+-----------------------
+Different types of makefiles (corresponding to a different compiler and/or
+operating system) can be added by subclassing from cmMakefileGenerator 
+(defined in cmMakefileGenerator.h/.cxx). Makefile generators process the 
+information defined by the commands in CMakeLists.txt to generate the
