The intention of this patch series is to make it as easy as possible for a Visual Studio user to start building Git from scratch. The idea is to * clone Git's source code, * open it in Visual Studio via File>Open>Folder... * let CMake configure things (and vcpkg build the dependencies, which will take a while), and * start the build. It does require a Git for Windows to be installed so that the source can be cloned, but also to run the shell script parts of the CMake configuration, and also to run the tests. This patch series replaces the patch "Ignore files generated by CMake" I sent via https://github.com/gitgitgadget/git/pull/735. Changes since v3: * Squashed the typo fix into the correct commit (d'oh!) * Fixed another typo (thanks, Sibi!) * Guarded the code block that initializes vcpkg and builds the dependencies behind the MSVC conditional (thanks, Sibi!) Changes since v2: * Fixed a typo in the message when msgfmt.exe is not found. * Simplified the logic to find sh.exe (thanks Øystein). Changes since v1: * Touched up a couple commit messages in response to reviewer comments * Adjusted the instructions at the top of CMakeLists.txt so that the part talking about running CMake manually also talks about using contrib/buildsystems/out/ as build directory (in line with the part talking about Visual Studio's out-of-the-box experience) * Replaced patch 10/10 with Junio's much more elegant solution of editing the hashmap_for_each_entry() macro instead of all of its callers.
