This command line tool was meant to generate a XML file (typically,
version.xml) containing the version numbers for a list of files defined
by the SD_INSTALL_FILES CMake macro. Then, the game would read this XML
file and copy files around if an update was needed.
Unfortunately, this introduced a circular dependency between the engine
and data repositories, as the engine repository would rely on the data
directory to know the file list, and the data repository would rely on
the xmlversion executable to be available, and therefore the engine
repository.
Ultimately, none of this was needed: it is much simpler to define a
static, line-separated list of files in the data repository, and then
let the game figure out the versioning by itself. This renders
xmlversion entirely redundant, and therefore breaks the circular
dependency. As a bonus, some overly complex CMake stuff could be
removed.
