CMake is the most similar to Bakefile from these. It generates

You mean if I generate a MinGW-makefile (e.g. makefile.gcc) from a
CMake -makefile I can not use it with MinGW alone (mingw32-make -f
makefile.gcc)? I need to have installed CMake?
Why? What is the technic behind it?
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.
