Instructions how to use this in Visual Studio:
Open the worktree as a folder. Visual Studio 2019 and later will detect
the CMake configuration automatically and set everything up for you,
ready to build. You can then run the tests in `t/` via a regular Git Bash.
Note: Visual Studio also has the option of opening `CMakeLists.txt`
directly; Using this option, Visual Studio will not find the source code,
though, therefore the `File>Open>Folder...` option is preferred.
Instructions to run CMake manually:
mkdir -p contrib/buildsystems/out
cd contrib/buildsystems/out
cmake ../ -DCMAKE_BUILD_TYPE=Release
This will build the git binaries in contrib/buildsystems/out
directory (our top-level .gitignore file knows to ignore contents of
this directory).
Possible build configurations(-DCMAKE_BUILD_TYPE) with corresponding
compiler flags
Debug : -g
Release: -O3
RelWithDebInfo : -O2 -g
MinSizeRel : -Os
empty(default) :
NOTE: -DCMAKE_BUILD_TYPE is optional. For multi-config generators like Visual Studio
this option is ignored
This process generates a Makefile(Linux/*BSD/MacOS) , Visual Studio solution(Windows) by default.
Run `make` to build Git on Linux/*BSD/MacOS.
Open git.sln on Windows and build Git.
NOTE: By default CMake uses Makefile as the build tool on Linux and Visual Studio in Windows,
to use another tool say `ninja` add this to the command line when configuring.
