Stephen Kelly b8af201168 cmTarget: Fix listing of source files at configure-time.
Since commit e5da9e51 (cmTarget: Allow any generator expression in
SOURCES property., 2014-03-18), source files are computed by
true evaluation of generator expressions, including TARGET_OBJECTS.
This evaluation requires the presence of cmGeneratorTarget objects
since commit bf98cc25 (Genex: Evaluate TARGET_OBJECTS as a normal
expression., 2014-02-26).

Ensure that we don't attempt to evaluate the TARGET_OBJECTS generator
expression at configure-time, as can happen if CMP0024 or CMP0026
are OLD.  Use old-style parsing of the source item to extract
object target names in that case.

Avoid calling GetProperty("SOURCES") to bypass warnings from CMP0051.
Refactor existing logic in GetLanguages which is similar in intent to
the new GetSourceFiles code.

Stephen Kelly 783bce295b Export: Disallow exported interface includes in src/build tree (#14592).
Allow directories in the source tree or build tree only if the
install tree is a subdirectory of the source tree or build tree,
as appropriate.

Re-use the test files in the RunCMake.include_directories test
to run in multiple scenarios.  Bump the required CMake version
in the test to 3.0 to ensure that the new policy warnings are
emitted correctly.

Stephen Kelly 4f1c71fdd2 cmTarget: Add all sources traced from custom commands at once.
The AddSource method accepts one file and tries to avoiding adding
it to the sources-list of the target if it already exists.  This
involves creating many cmSourceFileLocation objects for matching
on existing files, which is an expensive operation.

Avoid the searching algorithm by appending the new sources as one
group.  Generate-time processing of source files will ensure
uniqueness.

Add a new AddTracedSources for this purpose.  The existing
AddSources method must process the input for policy CMP0049, but
as these source filenames come from cmSourceFile::GetFullPath(),
we can forego that extra processing.

Stephen Kelly b1c3ae33ea cmTarget: Short-circuit language computation if context independent.
Computing the language involves computing the source files, which
is an expensive operation.  It requires calling
cmMakefile::GetOrCreateSource many times, which involves creating
and matching on many cmSourceFileLocation objects.

Source files of a target may depend on the head-target and the
config as of commit e6971df6 (cmTarget: Make the source files depend
on the config., 2014-02-13).  The results are cached for each context
as of commit c5b26f3b (cmTarget: Cache the cmSourceFiles in
GetSourceFiles., 2014-04-05).

Each target in the build graph causes language computation of all
of its dependents with itself as the head-target.  This means that
for 'core' libraries on which everything depends, the source files
are computed once for every transitive target-level-dependee and
the result is not cached because the head-target is different. This
was observed in the VTK buildsystem.

Short circuit the computation for targets which have a source-list
that is independent of the head-target.  If the source-list has
already been computed and the generator expression evaluation
reports that it was context-independent, return the only source-list
already cached for the target.  Reset the short-circuit logic when
sources are added and when the link libraries are re-computed.

Stephen Kelly 5412deded1 cmTarget: Transitively evaluate compiler features.
Extend the interface of the target_compile_features command with
PUBLIC and INTERFACE keywords. Populate the INTERFACE_COMPILER_FEATURES
target property if they are set. Consume the INTERFACE_COMPILER_FEATURES
target property from linked dependent targets to determine the final
required compiler features and the compile flag, if needed.

Use the same pattern of origin-debugging which is used for other
build properties.

Stephen Kelly eb163f37d4 cmTarget: Extract a ProcessSourceItemCMP0049 method.
Avoid calling AddSource for each src filename.  That involves
checking each entry for uniqueness and creating a separate
generator expression for each one.

Instead, add a single entry for the list of sources.  The source
files are passed through a uniqueness filter at generate-time, so
duplicates don't matter so much.

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.

Brad King f154475b65 cmTarget: Refactor GetLocation API
When given a non-NULL configuration the GetLocation returned the
location for the given configuration.  When given a NULL configuration
the GetLocation method returned a location with the build-system
placeholder for the configuration name.  Split the latter use case out
into a separate GetLocationForBuild method and update call sites
accordingly.

Ben Boeckel 270eb96df0 strings: Remove cmStdString references
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.

The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.

Brad King fba51b096e MSVC: Add properties to configure compiler PDB files (#14762)
Since commit v2.8.12~437^2~2 (VS: Separate compiler and linker PDB files
2013-04-05) we no longer set /Fd with the PDB_NAME or PDB_OUTPUT_DIRECTORY
properties.  Those properties now exclusively handle linker PDB files.
Since STATIC libraries do not link their compiler PDB file becomes more
important.  Add new target properties "COMPILE_PDB_NAME[_<CONFIG>]" and
"COMPILE_PDB_OUTPUT_DIRECTORY[_<CONFIG>]" to specify the compiler PDB
file location and pass the value to the MSVC /Fd option.

Stephen Kelly 5771f81d91 cmTarget: Add GetTransitiveTargetClosure method.
Replace calls to GetLinkInformation with calls to a method to get only
the target closure, not the link languages etc.  The replaced calls
are used while evaluating generator expressions only.  This makes
transitive generator expression evaluation independent from
the languages of a target.  In a follow-up topic, it will be possible
to make the languages depend on generator expression evaluation, via
evaluation of the SOURCES and INTERFACE_SOURCES target properties.

Because the order of entries is not the same as the final link line,
the order of debug output is different in the RunCMake.CompatibleInterface
test, because the BOOL_PROP7 target property is evaluated first. Adjust
the test to account for that new order.

Stephen Kelly b8b99cc1e5 cmTarget: Avoid computing languages when computing transitive targets.
For the OLD CMP0022 behavior, we need to treat the implementation
as the interface when computing the interface libraries.  Make it
possible to do that without computing the link languages by adding
a new GetLinkImplementationLibraries method.  Extend the existing
GetLinkImplementation method to populate the languages if the
libraries have already been computed and cached.

Change GetTransitivePropertyTargets to invoke GetLinkInterfaceLibraries
instead of GetLinkInterface.  This is key, as it is a method called
by cmGeneratorExpressionEvaluator.

Direct users of IMPORTED targets treat INTERFACE_INCLUDE_DIRECTORIES

use of an IMPORTED target would have the same behavior, but that

in cmTarget::FinalizeSystemIncludeDirectories.
