   7 Instructions how to use this in Visual Studio:
   8
   9 Open the worktree as a folder. Visual Studio 2019 and later will detect
  10 the CMake configuration automatically and set everything up for you,
  11 ready to build. You can then run the tests in `t/` via a regular Git Bash.
  12
  13 Note: Visual Studio also has the option of opening `CMakeLists.txt`
  14 directly; Using this option, Visual Studio will not find the source code,
  15 though, therefore the `File>Open>Folder...` option is preferred.
  16
  17 Instructions to run CMake manually:
  18
  19     mkdir -p contrib/buildsystems/out
  20     cd contrib/buildsystems/out
  21     cmake ../ -DCMAKE_BUILD_TYPE=Release
  22
  23 This will build the git binaries in contrib/buildsystems/out
  24 directory (our top-level .gitignore file knows to ignore contents of
  25 this directory).
  26
  27 Possible build configurations(-DCMAKE_BUILD_TYPE) with corresponding
  28 compiler flags
  29 Debug : -g
  30 Release: -O3
  31 RelWithDebInfo : -O2 -g
  32 MinSizeRel : -Os
  33 empty(default) :
  34
  35 NOTE: -DCMAKE_BUILD_TYPE is optional. For multi-config generators like Visual Studio
  36 this option is ignored
  37
  38 This process generates a Makefile(Linux/*BSD/MacOS) , Visual Studio solution(Windows) by default.
  39 Run `make` to build Git on Linux/*BSD/MacOS.
  40 Open git.sln on Windows and build Git.
  41
  42 NOTE: By default CMake uses Makefile as the build tool on Linux and Visual Studio in Windows,
  43 to use another tool say `ninja` add this to the command line when configuring.
