[PATCH v3 0/8] CMake build system for git

["Sibi Siddharthan via GitGitGadget" <gitgitgadget@gmail.com>]

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

Changes v2: Changes 1,2,4 have been rebased to PATCH 01/xx CMake uses
GIT-VERSION-GEN to get the version of Git

Sibi Siddharthan (8):
  Introduce CMake support for configuring Git
  cmake: generate the shell/perl/python scripts and templates,
    translations
  cmake: installation support for git
  cmake: support for testing git with ctest
  cmake: support for testing git when building out of the source tree
  cmake: support for building git on windows with mingw
  cmake: support for building git on windows with msvc and clang.
  ci: modification of main.yml to use cmake for vs-build job

     -    To make this a little less awkward, the Git for Windows project offers
     -    the `vs/master` branch which has a full Visual Studio solution generated
     -    and committed. This branch can therefore be used to tinker with Git in
     -    Visual Studio _without_ having to download the full Git for Windows SDK.
     -    Unfortunatly, that branch is auto-generated from Git for Windows'
     -    `master`. If a developer wants to tinker, say, with `pu`, they are out
     -    of luck.
     -
     -    CMake was invented to make this sort of problem go away, by providing a
     -    more standardized, cross-platform way to configure builds.
     +    The build infrastructure for Git is written around being able to run
     +    make, which is not supported natively on Windows.
     +    To help Windows developers a CMake build script is introduced here.
      
          With a working support CMake, developers on Windows need only install
          CMake, configure their build, load the generated Visual Studio solution

          With a CMake script an out of source build of git is possible resulting
          in a clean source tree.
      
     -    Note: earlier endeavors on the Git mailing list to introduce CMake ended
     -    up in dead water. The primary reason for that was that reviewers
     -    _expected_ CMake support to fall out of maintenance, unless the
     -    contributor would promise to keep an eye on keeping CMake support up to
     -    date. However, in the meantime, support for automated testing has been
     -    introduced in Git's source code, and a later patch will modify the
     -    (still experimental) GitHub workflow to continually verify that CMake
     -    support is still complete. That will make maintenance reasonably easy.
     -
          Note: this patch asks for the minimum version v3.14 of CMake (which is
          not all that old as of time of writing) because that is the first
          version to offer a platform-independent way to generate hardlinks as
          part of the build. This is needed to generate all those hardlinks for
          the built-in commands of Git.
      
     -    Instructions to run CMake:
     -
     -    cmake `relative-path-to-srcdir` -DCMAKE_BUILD_TYPE=Release
     +    Changes
     +    The CMake script parses the Makefile for:
     +    LIB_OBJS
     +    BUILTIN_OBJS
     +    XDIFF_OBJS
     +    VCSSVN_OBJS
     +    TEST_BUILTINS_OBJS
      
     -    Possible build configurations(-DCMAKE_BUILD_TYPE) with corresponding
     -    compiler flags
     -    Debug : -g
     -    Release: -O3
     -    RelWithDebInfo : -O2 -g
     -    MinSizeRel : -Os
     -    empty(default) :
     +    By doing this we avoid duplication of text between the Makefile and
     +    the CMake script.
      
     -    NOTE: -DCMAKE_BUILD_TYPE is optional
     +    The CMake script has been relocated to contrib/buildsystems.
      
     -    This process generates a Makefile.
     -    Then run `make` to build Git.
     -
     -    NOTE: By default CMake uses Makefile as the build tool on Linux, to use
     -    another tool say `ninja` add this to the command line when configuring.
     -    `-G Ninja`
     +    The CMake script uses GIT-VERSION-GEN to determine the version of Git
     +    being built.

          cmake: generate the shell/perl/python scripts and templates, translations
      
     -    This patch implements the placeholder substitution to generate, say,
     -    `git-request-pull` from `git-request-pull.sh`.
     +    Implement the placeholder substitution to generate scripted
     +    Porcelain commands, e.g. git-request-pull out of
     +    git-request-pull.sh
      
     -    The shell/perl/python scripts and template are generated using CMake
     -    (very similar to what sed does).
     +    Generate shell/perl/python scripts and template using CMake instead of
     +    using sed like the build procedure in the Makefile does.
      
          The text translations are only build if `msgfmt` is found in your path.
      
          NOTE: The scripts and templates are generated during configuration.
      
     +    Changes
     +    The CMake script parses the Makefile for:
     +    SCRIPT_SH
     +    SCRIPT_PERL

          ci: modification of main.yml to use cmake for vs-build job
      
     -    This patch modifies .github/workflows/main.yml to use CMake for
     -    Visual Studio builds.
     +    Teach .github/workflows/main.yml to use CMake for VS builds.
      
          Modified the vs-test step to match windows-test step. This speeds
          up the vs-test. Calling git-cmd from powershell and then calling git-bash
     @@ Commit message
          building git (eg zlib,libiconv). So we extract the libraries before we
          configure.
      
     -    Changes:
     -    The CMake script has been relocated to contib/buildsystems, so point
     -    to the CMakeLists.txt in the invocation commands.
     -
     -    The generation command now uses the absolute paths for the generation
     -    step.
     -
          To check for ICONV_OMITS_BOM libiconv.dll needs to be in the working
          directory of script or path. So we copy the dlls before we configure.
