   7 Instructions to run CMake:
   8
   9 cmake `relative-path-to-CMakeLists.txt` -DCMAKE_BUILD_TYPE=Release
  10 Eg.
  11 From the root of git source tree
  12         `cmake contrib/buildsystems/ `
  13 This will build the git binaries at the root
  14
  15 For out of source builds, say build in 'git/git-build/'
  16         `mkdir git-build;cd git-build; cmake ../contrib/buildsystems/`
  17 This will build the git binaries in git-build directory
  18
  19 Possible build configurations(-DCMAKE_BUILD_TYPE) with corresponding
  20 compiler flags
  21 Debug : -g
  22 Release: -O3
  23 RelWithDebInfo : -O2 -g
  24 MinSizeRel : -Os
  25 empty(default) :
  26
  27 NOTE: -DCMAKE_BUILD_TYPE is optional. For multi-config generators like Visual Studio
  28 this option is ignored
  29
  30 This process generates a Makefile(Linux/*BSD/MacOS) , Visual Studio solution(Windows) by default.
  31 Run `make` to build Git on Linux/*BSD/MacOS.
  32 Open git.sln on Windows and build Git.
  33
  34 NOTE: By default CMake uses Makefile as the build tool on Linux and Visual Studio in Windows,
  35 to use another tool say `ninja` add this to the command line when configuring.
  36 `-G Ninja`
