Merge branch 'ninja-object-library' into object-library

* ninja-object-library: (37 commits)
  Ninja: Honor $<TARGET_OBJECTS:...> source expressions
  Build object library targets in Ninja
  Pre-compute object file names before Ninja generation
  Simplify cmNinjaTargetGenerator using cmGeneratorTarget
  Ninja: Avoid using 'this' in member initializers
  Ninja: Fix for PDB files with spaces in the path.
  Ninja: Constify use of cmCustomCommand
  Ninja: add /DEF: flag to linker call
  Ninja: Add a cache option CMAKE_ENABLE_NINJA to enable the ninja generator.
  Ninja: Add friend struct so it can access the private ConvertToNinjaPath.
  Ninja: add .def file support
  Ninja: ensure the output dir exists at compile time
  Ninja: Remove an unnecessary variable
  Ninja: Use cmSystemTools::ExpandListArgument to split compile/link commands
  Ninja: Add a missed license header
  Ninja: CMake: Adapt Ninja generator for per-target include dirs
  Ninja: windows msvc: create for each target a .pdb file
  Ninja: Import library support for Windows
  Ninja: mark the Windows specific hacks with a comment only
  Ninja: disable unfinished Windows ninja support

+ * \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.
