/**
 * \class cmGlobalNinjaGenerator
 * \brief Write a build.ninja file.
 *
 * The main differences between this generator and the UnixMakefile
 * generator family are:
 * - We don't care about VERBOSE variable or RULE_MESSAGES property since
 *   it is handle by Ninja's -v option.
 * - We don't care about computing any progress status since Ninja manages
 *   it itself.
 * - We don't care about generating a clean target since Ninja already have
 *   a clean tool.
 * - We generate one build.ninja and one rules.ninja per project.
 * - We try to minimize the number of generated rules: one per target and
 *   language.
 * - We use Ninja special variable $in and $out to produce nice output.
 * - We extensively use Ninja variable overloading system to minimize the
 *   number of generated rules.
