Allow the `Swift` language to be enabled with the Xcode generator for
Xcode >= 6.1. Reject it on other generators and with older Xcode
versions. Since Apple is the only vendor implementing the language
right now, the compiler id can be just `Apple`.
The test for this variable was removed in commit v2.8.8~330^2~7 (complex:
Remove ancient unused ComplexRelativePaths test, 2011-12-23).
Commit v3.1.0-rc1~425^2~2 (backtrace: Convert to local paths in
IssueMessage, 2014-03-12) appears to have accidentally made some backtraces
print relative paths with the variable because conversions which used to be
done at configure time, before the variable had an effect are now potentially
done at generate time.
The documentation of the variable says not to use it, and the docs are wrong in
that the variable actually applies in per-directory scope.
The read of the variable makes it harder to split conversion methods from
cmLocalGenerator where they don't belong. Remove it now.
Refactor the local generator creation API to accept a
cmState::Snapshot. Adjust MakeLocalGenerator to use the 'current'
snapshot in cases where there is no parent. Create the snapshot
for subdirectories in cmMakefile::AddSubdirectory.
This means that snapshots are now created at the point of extending the tree,
as appropriate, and independently of the cmLocalGenerator and cmMakefile they
represent the state for.

7b68c8df Xcode: Sort Xcode objects by Id
this patch series aims to minimize deltas between the CMake Xcode
generator and Xcode itself. It was started by the observation that
if one makes any change to the project within Xcode (e.g. to see
how a variable is called internally) the user cannot diff the CMake
project and the one stored by Xcode afterwards.
Xcode keeps the objects ordered by the object id.
Because cmake stores them into an unordered container
at creation time they must be sorted before writing the
pbxproj file.
I tested this series with Xcode 6.3 and Xcode 3.2. Both show a
reduced diff after this series was applied.
This topic was never tested without some follow-up commits. The
GetCacheEntryValue API returns a pointer to memory freed on return.
It will have to be revised along with the rest of the original topic.
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.
The Ninja build system does not support a in-file verbositiy switch.
Instead teach 'cmake --build' to extract the CMAKE_VERBOSE_MAKEFILE
setting and pass it as an optional '-v' argument to Ninja. This can
serve as a reasonable fallback.

The "cmakexbuild" wrapper is not needed for Xcode 4 and above, and the
path to it may change when CMake moves. Avoid storing a specific path
to a build program in CMakeCache.txt and instead compute the value for
CMAKE_MAKE_PROGRAM on demand. However, if a user does set the value
explicitly then honor it.
This does for Xcode what commit v3.0.0-rc1~260^2~4 (VS: Switch to
internal CMAKE_MAKE_PROGRAM lookup by generators, 2013-11-15) did for
Visual Studio generators.
Extend the change made in commit v3.0.0-rc1~260^2~16 (Teach
GenerateBuildCommand to find its own make program, 2013-11-13) to have
the Xcode generator pick between "xcodebuild" and CMake's own copy of
"cmakexbuild" at build time based on the version of Xcode.
Teach the Xcode generator to compute the location of this tool or the
cmakexbuild wrapper. Add internal APIs to get the locations on demand.
Use the "cmakexbuild" wrapper for Xcode < 4, and "xcodebuild" for modern
Xcode.
The default target in XCode is the first one in the file.
In commit v3.1.0-rc1~286^2 (cmTarget: use a hash_map for cmTargets
typedef, 2014-06-10) the order of the targets stored in cmMakefile was
made non-deterministic instead of lexicographic. Teach the Xcode
generator to do its own sorting to restore a predictable order.
While at it, place ALL_BUILD first (as is done in VS IDE generators)
explicitly in the comparison function so that it is the default target
even if other targets sort earlier lexicographically (e.g. "AAA").
In commit v3.1.0-rc1~687^2~4 (cmTarget: Make the source files depend on
the config, 2014-02-13) an early termination case was added to the Xcode
generator. Fix handling of this case to actually abort all the
generation steps. Otherwise some of the later steps are attempted
without the preconditions normally established by earlier steps,
possibly leading to a crash.
Narrow down the decision if a CFBundle is built to one place.
This is a preparation patch to add another target property
which, if set, will imply BUNDLE. Having only one function
which will have to look at both properties helps to keep code
clean.

The Xcode generator uses Makefiles under a run-script build-phase to
drive custom commands. Fix the generated makefiles for custom commands
with multiple outputs to list all the outputs on the left hand side of
the build rule. This is much simpler and more reliable than the old
multiple-output-pair infrastructure.
A common idiom in CMake-based build systems is to have custom commands
that generate files not listed explicitly as outputs so that these
files do not have to be newer than the inputs. The file modification
times of such "byproducts" are updated only when their content changes.
Then other build rules can depend on the byproducts explicitly so that
their dependents rebuild when the content of the original byproducts
really does change.
This "undeclared byproduct" approach is necessary for Makefile, VS, and
Xcode build tools because if a byproduct were listed as an output of a
rule then the rule would always rerun when the input is newer than the
byproduct but the byproduct may never be updated.
Ninja solves this problem by offering a 'restat' feature to check
whether an output was really modified after running a rule and tracking
the fact that it is up to date separately from its timestamp. However,
Ninja also stats all dependencies up front and will only restat files
that are listed as outputs of rules with the 'restat' option enabled.
Therefore an undeclared byproduct that does not exist at the start of
the build will be considered missing and the build will fail even if
other dependencies would cause the byproduct to be available before its
dependents build.
CMake works around this limitation by adding 'phony' build rules for
custom command dependencies in the build tree that do not have any
explicit specification of what produces them. This is not optimal
because it prevents Ninja from reporting an error when an input to a
rule really is missing. A better approach is to allow projects to
explicitly specify the byproducts of their custom commands so that no
phony rules are needed for them. In order to work with the non-Ninja
generators, the byproducts must be known separately from the outputs.
Add a new "BYPRODUCTS" option to the add_custom_command and
add_custom_target commands to specify byproducts explicitly. Teach the
Ninja generator to specify byproducts as outputs of the custom commands.
In the case of POST_BUILD, PRE_LINK, and PRE_BUILD events on targets
that link, the byproducts must be specified as outputs of the link rule
that runs the commands. Activate 'restat' for such rules so that Ninja
knows it needs to check the byproducts, but not for link rules that have
no byproducts.
