:: REQUIRED ENVIRONMENT VARIABLES
:: This script requires to be executed inside one Visual Studio command line,
:: in order for many of the tools and environment variables to be available.
:: Additionally, it needs the following variables:
:: - CMAKE_BUILD_TYPE: Kind of build: Release, RelWithDebInfo, Debug.
:: - PYTHON_HOME: The Python installation directory.
:: - REPO_SCHEME: Optional. The scheme name to checkout.

:: REQUIRED PERMISSIONS
:: Practically, it is easier to be in the Administrators group to run the
:: script, but it should be possible to execute as a normal user.
:: The user will need permission to write files into the Windows SDK and the
:: VisualC++ folder.
