Ninja
-----

Generates build.ninja files.

A build.ninja file is generated into the build tree.  Recent versions
of the ninja program can build the project through the ``all`` target.
An ``install`` target is also provided.

For each subdirectory ``sub/dir`` of the project, additional targets
are generated:

``sub/dir/all``
  Depends on all targets required by the subdirectory.

``sub/dir/install``
  Runs the install step in the subdirectory, if any.

``sub/dir/test``
  Runs the test step in the subdirectory, if any.

``sub/dir/package``
  Runs the package step in the subdirectory, if any.

Fortran Support
^^^^^^^^^^^^^^^

The ``Ninja`` generator conditionally supports Fortran when the ``ninja``
tool has the required features.  As of this version of CMake the needed
features have not been integrated into upstream Ninja.  Kitware maintains
a branch of Ninja with the required features on `github.com/Kitware/ninja`_.
