CMake is used to compute dependencies in the makefiles, and variety of 
shell like
features in a cross platform way.  Also, it puts rules in the makefiles 
so that if an
input file to cmake changes, cmake will rerun and keep things up-to-date.
 CMake is also performs system introspection and finds the locations of 
libraries,
compilers and other things needed for the build.  This is similar to what a
configure script does.   However, a configure script depends on /bin/sh. 
 So, cmake needs to be run on the actual machine that you are building
on so that it can create makefiles that match that machine exactly.
