The linker will bring in shared libraries as a whole and use them even
for symbols that are needed by entries later in the link line.
Therefore we do not need to repeat them. De-duplicate link entries that
we know are shared libraries because we have a cmTarget associated with
them.

The cmGlobalGenerator::ResolveLanguageCompiler method, invoked only by
Makefile generators, contains code originally added by commit v2.4.0~796
(..., add new generators for msys and mingw, 2005-12-22) to compute the
full path to the compiler and save the result back into the cache value.
Since then the CMakeDetermine*Compiler modules have learned to resolve
the full path to the compiler and save it in CMake*Compiler.cmake files
configured in the build tree. The value of CMAKE_<LANG>_COMPILER in the
cache is now only for reference of what the user originally specified.
The full path is now available in a normal variable of the same name,
and this is used by project code and the generators.
When the user specifies -DCMAKE_<LANG>_COMPILER=name on the command-line
of an existing build tree that uses a Makefile generator, it is first
stored in the cache with an uninitialized type. Then later when
ResolveLanguageCompiler updates the cache entry and sets the type to
FILEPATH, cmMakefile::AddCacheDefinition does CollapseFullPath on the
"name" and ends up with something like "$PWD/name" which is unlikely to
be correct. Furthermore, cmMakefile::AddCacheDefinition proceeds to
remove the normal variable of the same name, so the value originally
saved in CMake<LANG>Compiler.cmake is ignored and the generators use the
wrong path to the compiler.
Resolve this by dropping the code from ResolveLanguageCompiler that
touches the cache value of CMAKE_<LANG>_COMPILER. As explained above it
is no longer needed anyway.
Since the Sanitizers write out one log file per process, a single
test might have more than one log file. This commit allows ctest
to read all of the log files found for a particual test.
In cmVisualStudio10TargetGenerator, add missing cmVS10EscapeXML
calls around paths to source and object files, custom command
dependencies and outputs, and platform name/version values.
Teach cmVisualStudioGeneratorOptions to encode FlagMap entries
and the FlagString value properly in vcproj/vcxproj XML files.
Update the one existing call site that pre-encoded the value
to not do so.
Some FlagMap entries are ;-lists. Store values as vector<string> so
that individual values may contain ';' characters. Delay the
construction of the final ;-list until writing to the VS project file.
With this approach the generated file may contain ;-separated values
that contain encoded ';' characters.
Delay conversion of the path to object files (on the left-hand side
of dependencies) until just before they are written. Also do not
convert the format of paths written to the 'depend.internal' file.
This is consistent with the way the right-hand side of dependencies
are already handled.
Make the virtual 'Generate' method protected. Make 'DoGenerate'
the main entry point to generation. This gives cmGlobalGenerator
a chance to do some early operations before the individual
generator-specific implementations take over.
In GetLinkInterface, GetLinkInterfaceLibraries, and
GetImportLinkInterface, lookup the HeadToLinkInterfaceMap for the
current configuration first, and then index it by head target. In
GetLinkImplementationLibrariesInternal, lookup the
HeadToLinkImplementationMap for the current configuration first, and
then index it by head target.
These use a huge amount of memory that accumulates as generation
proceeds. On the Unix Makefiles generator, only GetIncludeDirectories
and GetCompileDefinitions are even called more than once per target
(once for build files, once for dependency scanning preprocessor info).
Another approach will be needed to avoid duplicate computation in the
cases where it does occur.

Ask the global generator during generation instead of trying

the platform name when it is creating the local generator.
Move the definition of CMAKE_VS_PLATFORM_NAME and other variables that
are not needed by CMakeDetermineSystem out of the AddPlatformDefinitions
method and into a SetSystemName method. The latter may later use
CMAKE_SYSTEM_NAME to decide what platform-specific definitions to add.
Remove the general infrastructure for these additional platform
definitions and hard-code the only two special cases that used
it. They are only for historical reasons so no new such cases
should be added.
Add a cmGlobalGenerator::SetSystemName virtual method. Call it from
cmGlobalGenerator::EnableLanguage as soon as CMAKE_SYSTEM_NAME is known.
This will give generators a chance to adapt themselves to the target
system. Pass the cmMakefile instance to the method so that the
generator can update it accordingly. Return early from EnableLanguage
if SetSystemName returns false.
Make blocks adding MS-tool-specific options conditional on a

The LINK_LIBRARIES property is by *far* the most popular. Move it to the

6e7e881c Honor $<LINK_ONLY> when checking interface properties
0400cd5d Make $<LINK_ONLY> available to projects (#14751)
Replace isLinkDependentProperty with a CompatibleInterfaces structure
that records all the compatible interface properties in a set for each
type. This avoids repeatedly traversing the link implementation closure
and asking every target for its compatible interface properties.
In cmGeneratorExpressionEvaluator, teach getLinkedTargetsContent to call
cmGeneratorExpression::StripEmptyListElements to transform its return
value so that callers do not have to do so.
In cmGeneratorExpressionEvaluator, avoid searching through the list of
transitive interface property names repeatedly during evaluation of
TargetPropertyNode. Simply record the results of the first search for
later re-use.
In cmGeneratorExpressionEvaluator, make getLinkedTargetsContent a
template so it can traverse over either the Libraries in a cmTarget
LinkImplementationLibraries or a cmTarget LinkInterfaceLibraries. This
also avoids creating a separate vector<cmTarget*>.
Since commit v3.0.0-rc1~174^2~1 (cmTarget: Fix system include annotation
propagation, 2014-01-01) the cmGeneratorTarget::IsSystemIncludeDirectory
method needs to collect all targets that might provide
INTERFACE_(|SYSTEM)_INCLUDE_DIRECTORIES for the current target. We now
have cmTarget::GetLinkImplementationClosure to provide this, so use it.
Split the library lists out of LinkImplementation and LinkInterface into
LinkImplementationLibraries and LinkInterfaceLibraries parent classes,
respectively. Return these from GetLinkImplementationLibraries and
GetLinkInterfaceLibraries, respectively, so that callers cannot access
parts of the structures that have not been populated.
Callers of cmTarget::GetLinkImplementationClosure are interested in the
set of targets whose interface properties propagate to the current
target. This excludes targets guarded by $<LINK_ONLY>.
Teach the CompatibleInterface test to cover suppression of interface
compatibility tests with $<LINK_ONLY>. Although this is not recommended
in practice, it is a way of covering the above behavior.
Previously this generator expression was used internally by the
target_link_libraries command to honor private linking requirements of
static libraries in their INTERFACE_LINK_LIBRARIES. Remove the check
that limits $<LINK_ONLY> to this use case to make it available for
project code to use too.
Before this commit, you would have to run ctest -S mode to get
MemoryCheckType to work. This is because CMAKE_COMMAND was not set.
The fix is to use cmSystemTools::GetCMakeCommand instead.
This adds support for memory and leak sanitizers. This is built into
clang and gcc 4.8 and new compilers. It is activated with a -f switch
during compile.

Use the AddInterfaceEntries helper to avoid duplication. In
TargetPropertyEntry, replace the TargetName string member with a
reference to the full cmLinkImplItem that produced the entry. This is
possible because the cmLinkImplItem is available in AddInterfaceEntries
(it was not available in GetIncludeDirectories). Having the full
cmLinkImplItem allows processIncludeDirectories to implement CMP0027 OLD
behavior without repeating the target name lookup.
Update the RunCMake.CompatibleInterface test DebugProperties case
expected output for the new order of the messages.
Evaluate and lookup the target name only once per TargetPropertyEntry
instead of repeating it for each include directory entry. Use a local
checkCMP0027 variable to record whether the policy should be checked.
Evaluate the target name as a generator expression only if it looks like
one. Lookup the target by name only after evaluation of generator
expressions.
Implementation of CMP0027 OLD behavior needs to know whether each entry
in LinkImplementation::Libraries came from a generator expression or
not. Add a FromGenex member to cmLinkImplItem to record this.
Create a cmTargetInternals::AddInterfaceEntries method to construct a
$<TARGET_PROPERTY:tgt,INTERFACE_XYZ> generator expression and evaluate
it for every target in the link implementation. This will be useful to
de-duplicate such evaluation for each usage requirement separately.
The new method will soon be used in the implementation of the
INTERFACE_* usage requirement lookup methods (GetSourceFiles,
GetCompileOptions, GetCompileDefinitions, GetCompileFeatures,
GetIncludeDirectories). It is necessary for these methods to determine
whether an expression in LinkImplementationPropertyEntries evaluates to
a target or not because generator expression evaluation reports an error
for non-targets and we construct a $<TARGET_PROPERTY:tgt,INTERFACE_XYZ>
expression for each entry that is a target.
The implementation of each usage requirement currently processes the
LinkImplementationPropertyEntries and evaluates all generator
expressions to determine targets. That is no longer necessary because
GetLinkImplementationLibraries now returns resolved and cached targets
together with their name. Use it to implement AddInterfaceEntries.
Create a cmLinkImplItem class derived from cmLinkItem so more
information can be added to link implementation entries than link
interface entries. Convert the LinkImplementation Libraries member to
hold it. Update client sites accordingly.
Send status messages to the CTest HANDLER_OUTPUT log since they are part
of the script handler output. This also ensures they appear inline with
other test command handler output.
Because the 8bit string encoding in libarchive can be different than
the 8bit string encoding in CMake, change to call the wide version
of libarchive functions. They are different if CMake is configured
to use UTF-8 as the internal encoding.
Create helper functions for some libarchive calls to use wstring
internally on platforms supporting it.
Commit v2.8.11~310^2~1 (Keep track of INCLUDE_DIRECTORIES as a vector of
structs., 2012-11-19) added special case of INCLUDE_DIRECTORIES
for the purpose of origin-tracking of individual entries in the property. It
introduced a bug in that it returned an empty string instead of '0' in the
case that no includes have been set.
Commit v2.8.11~289^2~2 (Handle INTERFACE properties transitively for includes
and defines., 2012-09-23) introduced transitive handling of the property
through the link implementation, together with a whitelist of properties
which would be evaluated transitively. Because of the bug introduced
previously, the 'prop' in TargetPropertyNode is non-null,
meaning that the content (the empty string) would be evaluated as a generator
expression. This was harmless as the follow-up code was only for 'INTERFACE_'
variants of target properties, so the effect was the same.
Commits v2.8.11~280^2~2 (Keep track of properties used to determine linker
libraries., 2012-11-05) and v2.8.11~280^2~1 (Add API to calculate
link-interface-dependent bool properties or error., 2013-01-06) added a way
to track and report errors on properties which both determine and are
determined by the link implementation. This was later used in generator
expression evaluation by commit v2.8.11~252^2~2 (Make INTERFACE determined
properties readable in generator expressions., 2013-01-19). If a property
is unset (null), and the link implementation of the target was not being
evaluated, this commit made it possible to evaluate the property from the
link implementation instead. If the link implementation was being evaluated,
an empty string was returned from the generator expression evaluation, which
might be later reported as an error.
The above logic was written for 'compatible interface' properties, but in
fact it should have also included other properties. Because of the
empty-string-instead-of-null bug, this code block is not entered for the
INCLUDE_DIRECTORIES property. At this point, however, the bug still does
not significantly affect behavior, because the follow-up code is still a
no-op for the INCLUDE_DIRECTORIES property, and an empty string is returned
regardless. Commit v2.8.11~189^2~6 (Use the link information as a source of
compile definitions and includes., 2013-02-12) refactored the logic, but also
without a change in behavior.
Commit v2.8.11~156^2~2 (Expand includes and defines transitively
in 'external' genexes., 2013-02-13) refactored the logic again, this time with
a change of behavior. The INCLUDE_DIRECTORIES property was then mapped to
INTERFACE_INCLUDE_DIRECTORIES during transitive generator expression
evaluation. Because the transitive evaluation involved evaluation of the
link implementation, this introduced a recursive loop and a segfault with
code like:
add_library(empty1 ...)
add_library(empty2 ...)
target_link_libraries(empty1
PRIVATE
$<$<STREQUAL:$<TARGET_PROPERTY:INCLUDE_DIRECTORIES>,/foo/bar>:empty2>
)
As there is no real use-case for reading a target property like that while
evaluating the link implementation, this went unnoticed. The same pattern
was followed for other special-cased reads of transitive target properties
such as COMPILE_DEFINITIONS.
The segfault was fixed in the parent commit, but change the property to
return null when appropriate for other future uses.
Commit v2.8.11~156^2~2 (Expand includes and defines transitively
in 'external' genexes., 2013-02-13) introduced a recursive loop
and a stack overflow during evaluation of a link implementation
which depends on a transitive property, such as
add_library(empty1 ...)
add_library(empty2 ...)
target_link_libraries(empty1
PRIVATE
$<$<STREQUAL:$<TARGET_PROPERTY:INCLUDE_DIRECTORIES>,/foo/bar>:empty2>
)
There is no use-case for code like that currently, but it should not
cause a stack overflow.
Avoid the recursion by reporting an error early if a case like this
is found.
A library or executable target that consists only of a reference to an
object library may have no sources to compile or custom commands to run.
The command in the target is the link (or archive) command. Add missing
order-only dependencies to link commands so that target ordering
dependencies are satisfied for it without depending on an intermediate
compilation rule.
Extend the ObjectLibrary test to cover this case.

Ninja generator ensures that all custom commands being target
dependencies are run before other source compilations. However in case
there are no such dependencies it currently generates empty phony rules
which clutter the build graph.
Teach the Ninja generator to produce such rules only when necessary.
Actually custom command can write wherever it wants to, such as temporary
folder or source folder, possibly violating rules that only build folder should
be affected. Therefore we should consider custom command dependency at any path
as possible side effect adding phony rule.
We avoid adding phony rules for regular source files (since the paraent
commit) so we no longer need the in-build-tree test to avoid them.
Since commit v2.8.12~248^2 (Ninja: Custom Command file depends don't
need to exist before building, 2013-06-07) all explicit dependencies
inside build folder were considered as possible build command
side-effects and phony rules were produced for them in case they don't
exist when starting to build. This is unnecessary since regular compile
inputs need to exist or cmake will fail. Moreover the exception for
sources having GENERATED property that can be missing is already handled
by WriteAssumedSourceDependencies.
This fixes unwanted phony rules for all regular source files when doing
in-source build, causing Ninja not complain when such files gets missing,
i.e. during development. Also this reduces number of rules in ninja.build.
Now only custom command dependencies are considered as possible side-effects.
