Revert commit 6fac24d7 (Ninja: Avoid re-running CMake on next build
after regeneration, 2014-01-09). The files reported by the method
cmMakefile::GetOutputFiles() must cause CMake to re-run only if they are
missing and without considering a timestamp. Therefore they cannot be
listed as outputs of the re-run rule or Ninja will re-run CMake every
time because the timestamp of configure_file outputs does not change.
Another solution will have to be found to the original problem.
When not installing in /usr (i.e. /usr/local) on Debian/Ubuntu, the
multiarch path is not in ldconfig path, and therefore libraries cannot
be found, unless the user manually modifies the files in
/etc/ld.so.conf.d, in order to include /usr/local/lib/<arch>.
This patch fixes this issue by using "lib/<arch>" only if the user is
installing the software in /usr, and uses "lib" in all the other cases.
Remove independent doc listing for Qt4ConfigurationSettings, Qt4Macros
and UseQt4. These are implementation details.
Recommend the use of IMPORTED targets.
Remove references to the UseQt4 file, which is obsolete in light of
the IMPORTED targets.
Add documentation for automatic tool invocation and options.
Remove reference to variables which should not be needed in modern
implementations.

In commit 4a6397a7 (Ninja: Track configured files so we can regenerate
them, 2013-06-17) we accidentally started listing files generated by
CMake as inputs to the configuration process instead of outputs from it.
Move the list of files generated by CMake to the regeneration rule
outputs section and tell Ninja to restat after running it.
Create cmGeneratorTargets before generating generate-time information.
C++ interfaces for querying build information is increasingly only
available at generate time through the cmGeneratorTarget class. Ensure
that the required cmGeneratorTarget instances are created. Use the
cmGlobalGenerator access API to access the relevant cmGeneratorTarget
instead of creating a temporary one on the stack.
Commit 5bb53f6b (cmTarget: Deprecate COMPILE_DEFINITIONS_ properties
with a policy., 2013-12-30) deprecated the config-specific
COMPILE_DEFINITIONS_* properties in favour of using generator
expressions.
Set the directory property in UseQt4.cmake to match the
INTERFACE_COMPILE_DEFINITIONS on the Qt4::QtCore and Qt5::Core
IMPORTED targets. Setting QT_NO_DEBUG is sufficient because qglobal.h
sets the corresponding QT_DEBUG definition if required.
The all target was depending on the clean and pngtest targets, but
when running the tests with -jN, those can be executed out of order.
Make the main.o target depend on the clean target instead to fix
this.
