The Makefile is not going to be replaced at all. The CMake script for now only supports Linux and Windows. It does not support BSD, Solaris and others, whereas the Makefile does support them. The reason for introducing CMake is primarily for compiling git on Windows and to do out of source builds. I think the CMake script makes it easier to build Git as it does the necessary function and header checks and generates the required compile definitions. I would like to say that the proposed CMake build system is meant to complement the currently used Makefile, not to replace it at all. Thank You, Sibi Siddharthan PS: Sorry for the multiple emails:)
