The rcc outputs are byproducts of the cmake_autogen rule, not outputs.
We still must run cmake_autogen on every run even if the rcc outputs
exist. Ninja requires explicit byproduct specification, which is now
possible in CMake since commit v3.2.0-rc1~340^2~2 (Add an option for
explicit BYPRODUCTS of custom commands, 2014-11-13). Revise the logic
introduced by commit v3.2.0-rc1~480^2 (QtAutogen: Regenerate qrc files
if their input changes, 2014-09-17) to specify byproducts explicitly.
Teach the Xcode generator that ONLY_ACTIVE_ARCH=YES means to use ARCHS,
and that the default of ONLY_ACTIVE_ARCH=NO means to use NATIVE_ARCH and
ignore ARCHS. In the latter case there is no reason to generate ARCHS.
"XML_Parser" in cmexpat is a typedef for void* while newer releases of
expat seem to use struct XML_ParserStruct *XML_Parser.
Add static_casts so that the build works with either variant.
The file lock functionality added in commit v3.2.0-rc1~297^2~1 (file:
Add LOCK subcommand to do file and directory locking, 2014-11-26) forgot
to close the lock file descriptors. Eventually it was possible to run
out of file descriptors and locks could not longer be acquired. Fix
this by closing the file descriptor or handle when we are done with it.
Also set the member back to the initial value from the constructor
to leave everything in a consistent state (useful for debugging).

Add policy CMP0058 to avoid generating 'phony' ninja rules for unknown
custom command dependencies. This requires projects to specify their
custom command byproducts explicitly. With this requirement we no
longer have to assume that unknown custom command dependencies are
generated and can instead simply assume they are source files expected
to exist when the build starts. This is particularly important in
in-source builds. It is also helpful for out-of-source builds to allow
Ninja to diagnose missing files before running custom command rules that
depend on them.
Teach WriteUnknownExplicitDependencies to take ownership of the set of
WriteBuild outputs immediately since no other methods need the data.
This avoids re-inserting the whole set into another already populated
set.
GLOB lists directories by default and GLOB_RECURSE does not.
LIST_DIRECTORIES enables user to control the behavior explicitly for
consistently for both GLOB and GLOB_RECURSE.
The phony rules added by commit v2.8.12~248^2 (Ninja: Custom Command
file depends don't need to exist before building, 2013-06-07) are
circular, e.g.
build side-effect: phony side-effect
This is not diagnosed by Ninja as of version 1.5, but the dependency
does not make sense. Simply drop it and use phony rules of the form
build side-effect: phony
instead.
