Brad King ab9fa54d48 Xcode: Switch to internal CMAKE_MAKE_PROGRAM lookup by generator (#15324)
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.

Brad King 11e2e6cadf Xcode: Select make program at build time
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.

Brad King e4055a6144 Xcode: Add internal API to find xcodebuild
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.

Ben Boeckel 9e0176e2b3 Xcode: Sort targets deterministically and with ALL_BUILD first (#15346)
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").

Brad King c0ff542c58 Xcode: Fix early termination on per-config source file error
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.

Gregor Jasny 3a605693a5 Xcode: Call IsCFBundleOnApple to decide if bundle is being built
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.

Brad King 8a4c6d2d2e Xcode: Fix rebuild with multiple custom command outputs (#15116)
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.

Brad King e15a7075b5 Add an option for explicit BYPRODUCTS of custom commands (#14963)
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.

Xcode requires a separate PBXFileReference for each target source group

Brad King 608cf8149c Xcode: Fix static library creation for Xcode 6 (#15038)
Xcode 6 introduced an 'OTHER_LIBTOOLFLAGS' setting for the "Other
Librarian Flags" of a static library.  Now 'OTHER_LDFLAGS' are ignored.
Teach the Xcode generator to choose the correct name for the build

Brad King 0dc9e88d76 cmTarget: Remove 'head' argument from GetLinkImplementation
Many of the 'head' arguments added by commit v2.8.11~289^2~1 (Make
linking APIs aware of 'head' target, 2013-01-04) turned out not to be
needed.  The "link implementation" of a target never needs to be
computed with anything but itself as the 'head' target (except for
CMP0022 OLD behavior because then it is the link interface).

Remove the unused 'head' target paths.  Add "internal" versions of
cmTarget::GetDirectLinkLibraries and GetLinkImplementationLibraries
to support the CMP0022 OLD behavior without otherwise exposing the
'head' target option of these methods.

Brad King 23dc6aa194 Xcode: Fix single-configuration generation for version 1.5
In commit 84fdc992 (stringapi: Pass configuration names as strings,
2014-02-09) a few code paths for the Xcode 1.5 single-configuration
generator were not updated to use an empty configuration name instead of
a NULL pointer when no configuration is specified in CMAKE_BUILD_TYPE.
Fix them now.

Brad King 528e8af19f Allow a toolchain file to specify a generator toolset
Delay use of CMAKE_GENERATOR_TOOLSET until the CMakeSystem.cmake
file has been configured and loaded during the first project() or
enable_language() command.  This gives the toolchain file named by
CMAKE_TOOLCHAIN_FILE a chance to set CMAKE_GENERATOR_TOOLSET.  This
point is still early enough to set the generator toolset prior to
the initialization of any languages that might use the toolset.

The cmake::GeneratorToolset member variable remains an indication
of what was specified by the -T option or loaded from the cache.
It does not need to be updated based on the toolchain file setting.
The cmMakefile::TryCompile can still pass cmake::GeneratorToolset
into the inner instance because the try-compiled project will do
platform and language initialization using the CMakeSystem module
configured for the outer project.

Extend the RunCMake.GeneratorToolset test with cases that use a
toolchain file to set CMAKE_GENERATOR_TOOLSET.

Stephen Kelly e6971df6ab cmTarget: Make the source files depend on the config.
Disallow the use of config-specific source files with
the Visual Studio and Xcode generators. They don't have
any way to represent the condition currently.

Use the same common-config API in cmQtAutoGenerators. While
it accepts config-specific files, it doesn't have to support
multiple configurations yet.

Loop over the configs in cmTargetTraceDependencies
and cmGlobalGenerator::WriteSummary and consume all source
files.

Loop over the configs in cmComputeTargetDepends and compute the
object library dependencies for each config.

Stephen Kelly aa0a3562dd cmGeneratorTarget: Compute target objects on demand
Add a ComputeObjectMapping method to compute the object
names.  It takes mapping to populate as an out-parameter so
that it can be extended in the future with parameters
relevant to generator expression evaluation.

Remove the supporting cmGeneratorTarget::AddObject method. It is
no longer needed as the container member is populated directly.

The ComputeObjectMapping method is called whenever objects are
requested from the cmGeneratorTarget.  Because the Xcode generator
makes no such request, explicitly invoke the method from that
generator so that the logic of checking for bad sources in object
libraries is executed.

In a follow-up, the UseObjectLibraries usage may be replaced by a
true generator expression evaluator for TARGET_OBJECTS. That
will require generators to use cmGeneratorTarget::GetExternalObjects
which is not currently the case for Xcode and VS generators.

Stephen Kelly e5da9e51d0 cmTarget: Allow any generator expression in SOURCES property.
Remove use of UseObjectLibraries from Makefile and Ninja generators. It
is not needed now because those generators use GetExternalObjects
which already contains the objects from object libraries.

The VS10 generator calls both the UseObjectLibraries and the GetExternalObjects
methods. Ensure that duplicates are not created by skipping objects
from object libraries in handling of GetExternalObjects.

Similarly, fix VS6, VS7 and Xcode object handling by skipping
external objects from OBJECT_LIBRARY usage as appropriate.

The error message in the BadSourceExpression1 test is now reported
by the generator expression evaluator, so it has different text.

modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.
