/**

* \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.
