Building from Git Sources ------------------------- Please use `--recurse-submodules` option with the initial `git clone`. If you had already cloned the repository without this option, please run `git submodule update --init` to also get all 3rd party libraries code. Before building from Git sources under Windows, you need to copy the file `include/wx/msw/setup0.h` to `include/wx/msw/setup.h`. This is necessary in order to allow having local modifications to the latter file without showing it as modified, as it is not under version control. After doing this, please proceed with the build as with any official release, i.e. follow the instructions in the port-specific files, e.g. [wxMSW](docs/msw/install.md), [wxGTK](docs/gtk/install.md), [wxOSX](docs/osx/install.md) and so on.
