[Arnout:
 - keep DEVELOPERS alphabetical;
 - use oatpp for the prompt;
 - add threads to the toolchain dependencies comment;
 - move comment after the main prompt;
 - rewrap the help text;
 - empty line before upstream URL;
 - hash comment Locally calulated instead of pointing to upstream
   tarball URL;
 - change hash to sha256;
 - add hash for license file;
 - reorder variables in .mk file;
 - use _CONF_OPTS instead of invalid _CMAKE_OPTS.
