This is an attempt to build Git using CMake. CMake is cross-platform build
generator which works well on a variety of platforms(primarily Linux and
Windows). Using CMake we can check whether certain headers exist, certain
functions exist, the required libraries are present and configure the build
accordingly. Using CMake we can also build and test Git out of source,
resulting in a clean source tree.

Tested platforms

Ubuntu 18.04 GCC 7.4 Clang 8.0.1

Windows MinGW GCC 9.2 Clang 9 Visual Studio 2015,2017,2019

Changes:

1) The CMake script has been relocated to contrib/buildsystems 2) The CMake
script parses the Makefile for the sources. 3) Philip suggested to change
the error message if sh/bash was not found on windows. 4) CMake now tests
for ICONV_OMITS_BOM, NO_ST_BLOCKS_IN_STRUCT_STAT
