In commit v3.6.0-rc1~279^2~10 (VS: in Clang/C2 toolset, setup correct
compiler settings, 2016-02-18) a flag mapping was added for the clang
`-Os` flag. However, this collides with a mapping we already had for
the MSVC flag of the same name. This is a symptom of a larger problem
in that the VS generators need a per-toolset flag map (issue #16153).
For now, simply drop the new mapping and drop `-Os` from clang compiler
flags in the MinSizeRel configuration.

Since 2.6.3 the UTILITY target may have source files. A defect was filed
that these files are now visible in the source tree. A fix later removed
all generated files from the source tree, regardless of the target type.
You can't even include them by using the SOURCES option. This fix adds
generated files again, except for the UTILITY target which cluttered the
source tree.
Fixes#14272.

The force parameter is ugly and makes the method harder to reason about
(issues the message ... but maybe it doesn't ... but then again you can
force it). It is a violation of
https://en.wikipedia.org/wiki/Interface_segregation_principle
and is the kind of thing described in a recent blog here:
http://code.joejag.com/2016/anti-if-the-missing-patterns.html
"Any time you see this you actually have two methods bundled into one.
That boolean represents an opportunity to name a concept in your code."
The makefile is only used when called by the cmMessageCommand, so inline
the use of it there. It otherwise creates an undesirable dependency on
cmMakefile for issuing messages in the cmake instance, a violation of
the Interface Segregation Principle.
https://en.wikipedia.org/wiki/Interface_segregation_principle
This also makes it more explicit that the variable definitions only
affect the message() command. If an AUTHOR_WARNING is issued for any
other reason, it is not affected. To affect that, it is necessary to
set the cache variable instead of the regular variable.
This is an unfortunate interface quirk, but one which can't be fixed
easily now.
Add a ``FIND_LIBRARY_USE_LIB32_PATHS`` global property analogous to the
``FIND_LIBRARY_USE_LIB64_PATHS`` property. This helps find commands on
multilib systems that use ``lib32`` directories and either do not have
``lib`` symlinks or point ``lib`` to ``lib64``.
When we are on OSX and we are launching cmake-gui from a symlink, the
application will fail to launch as it can't find the qt.conf file which
tells it what the name of the plugin folder is. We need to add this path
BEFORE the application is constructed as that is what triggers the
searching for the platform plugins

Policy CMP0026 deprecated the LOCATION property, and we have long
provided a $<TARGET_FILE:...> generator expression. However, if
a project tries to use $<TARGET_PROPERTY:...,LOCATION> we should
at least not crash.
The compatibility implementation of the LOCATION property uses
cmGlobalGenerator::CreateGenerationObjects to create the structures
needed to evaluate the property before generation starts. The
implementation assumed that accessing the property could only be done
during configuration (via the typical get_property command use case).
The $<TARGET_PROPERTY:...,LOCATION> genex causes the LOCATION property
to be accessed during generation. Calling CreateGenerationObjects
during generation blows away all the objects currently being used for
generation and is not safe. Add a condition to call it only when
configuration is not finished.

Update our own implementation to avoid warnings with flex types.
Even though the `file(GLOB)` documentation specifically warns against
using it to collect a list of source files, projects often do it anyway.
Since it uses `readdir()`, the list of files will be unsorted.
This list is often passed directly to add_executable / add_library.
Linking binaries with an unsorted list will make it unreproducible,
which means that the produced binary will differ depending on the
unpredictable `readdir()` order.
To solve those reproducibility issues in a lot of programs (which don't
explicitly `list(SORT)` the list manually), sort the resulting list of
the `file(GLOB)` command.
A more detailed rationale about reproducible builds is available
[here](https://reproducible-builds.org/).
Add a `CMAKE_NINJA_OUTPUT_PATH_PREFIX` variable. When it is set, CMake
generates a `build.ninja` file suitable for embedding into another ninja

In WriteObjectBuildStatement we pass object file names and directories
to several places that expect paths as Ninja sees them. Convert them to
Ninja paths before all such uses.
All paths generated on Ninja-invoked command lines should be passed
through ConvertToNinjaPath. Fix ConvertToLinkReference to call this
instead of partially duplicating its implementation.
In `AppendTargetOutputs` we generate a logical build target name for
each UTILITY command. Simplify the logic to avoid testing the result
of `ConvertToNinjaPath`.

Clang-Tidy writes the number of warnings, the number of suppressed
warnings, and instructions on how to suppress warnings to stderr. Since
each source file is checked individually, this repetitive information is
disturbing and should be suppressed.
The actual warning messages are written to stdout. Some IDEs (eg.
QtCreator) analyze only stderr for issues. Redirecting Clang-Tidy's
stdout to stderr makes sure the warnings are correctly displayed.
To avoid Race conditions with other processes writing to stdout/stderr compose
the whole message in a std::stringstream then submit the single complete message.

All callers now pass a full backtrace so we do not need the alternative
that takes a cmListFileContext directly. Drop this overload to remove
the code duplication.
Since commit v3.4.0-rc1~321^2~2 (Genex: Store a backtrace, not a pointer
to one, 2015-07-08) we treat cmListFileBacktrace instances as
lightweight values. This was true at the time only because the
backtrace information was kept in the cmState snapshot hierarchy.
However, that forced us to accumulate a lot of otherwise short-lived
snapshots just to have the backtrace fields available for reference by
cmListFileBacktrace instances. Recent refactoring made backtrace
instances independent of the snapshot hierarchy to avoid accumulating
short-lived snapshots. This came at the cost of making backtrace values
heavy again, leading to lots of string coying and slower execution.
Fix this by refactoring cmListFileBacktrace to provide value semantics
with efficient shared storage underneath. Teach cmMakefile to maintain
its call stack using an instance of cmListFileBacktrace. This approach
allows the current backtrace to be efficiently saved whenever it is
needed.
Also teach cmListFileBacktrace the notion of a file-level scope. This
is useful for messages about the whole file (e.g. during parsing) that
are not specific to any line within it. Push the CMakeLists.txt scope
for each directory and never pop it. This ensures that we always have
some context information and simplifies cmMakefile::IssueMessage.
Push/pop a file-level scope as each included file is processed. This
supersedes cmParseFileScope and improves diagnostic message context
information in a few places. Fix the corresponding test cases to expect
the improved output.
Changes during post-3.3/pre-3.4 development refactored storage of most
configure-time information, including variable bindings and function
scopes. All scopes (even short-lived) were kept persistently for
possible future debugging features, causing huge accumulated memory
usage. This was mostly addressed by commit v3.4.1~4^2 (cmState: Avoid
accumulating snapshot storage for short-lived scopes, 2015-11-24).
Since then we still keep short-lived scopes when they are needed for a
backtrace. This is because since commit v3.4.0-rc1~378^2
(cmListFileBacktrace: Implement in terms of cmState::Snapshot,
2015-05-29) backtraces have been lightweight objects that simply point
into the snapshot tree. While the intention of this approach was to
avoid duplicating the call stack file path strings, the cost turned out
to be holding on to the entire call stack worth of scope snapshots,
which is much worse.
Furthermore, since commit v3.4.0-rc2~1^2 (cmIfCommand: Issue CMP0054
warning with appropriate context, 2015-10-20) all conditions used in
`if()` commands hold a backtrace for use in diagnostic messages. Even
though the backtrace is short-lived it still causes the scope snapshot
to be kept. This means that code like
function(foo)
if(0)
endif()
endfunction()
foreach(i RANGE 1000000)
foo()
endforeach()
accumulates storage for the function call scope snapshots.
Fix this by partially reverting commit v3.4.0-rc1~378^2 and saving the
entire call stack during cmListFileBacktrace construction. This way
we can avoid keeping short-lived scope snapshot storage in all cases.
In commit v2.8.4~32^2~14 (Use cmake::IssueMessage for warnings,
2010-12-07) these warnings became formatted. It is more informative to
give the full call stack with such warnings. Also it is easier to
implement warnings with a full call stack because we do not have to
construct a custom backtrace with only the top.
This method was added by commit v3.4.0-rc1~424^2~6 (cmLocalGenerator:
Add IssueMessage method, 2015-06-13) in order to reduce callers'
dependency on cmMakefile. Currently the implementation of
cmLocalGenerator::IssueMessage is just a copy of the post-configure code
path in cmMakefile::IssueMessage. De-duplicate the implementation by
simply calling the cmMakefile copy for now. This will simplify upcoming
refactoring of backtraces. The dependency on cmMakefile can be removed
by future work once that is done.
Create a <LANG>_CLANG_TIDY target property (initialized by a
CMAKE_<LANG>_CLANG_TIDY variable) to specify a clang-tidy command line
to be run along with the compiler.
In the `try_compile` source file signature we propagate the caller's
value of `CMAKE_<LANG>_FLAGS` into the test project. Extend this to
propagate `CMAKE_<LANG>_FLAGS_<CONFIG>` too instead of always using the
default value in the test project. This will be useful, for example, to
allow the MSVC runtime library to be changed (e.g. `-MDd` => `-MTd`).

The change in commit v3.5.0-rc1~198^2 (Ninja: Always re-run custom
commands that have symbolic dependencies, 2015-11-19) broke the
byproducts feature added by commit v3.2.0-rc1~340^2~2 (Add an option for
explicit BYPRODUCTS of custom commands, 2014-11-13) when SYMBOLIC
outputs also appear. This case occurs with AUTORCC-generated custom
targets because the output is SYMBOLIC (to always run) and the generated
file is a byproduct (for restat so dependents do not run unnecessarily).
The two use cases conflict because Ninja does not support per-output
restat. Favor restat whenever byproducts are present because it is
required for byproducts to work correctly. In use cases where we want
an always-run chain we simply will not be able to also use byproducts.
Fix logic introduced by commit v3.5.0-rc1~198^2 (Ninja: Always re-run
custom commands that have symbolic dependencies, 2015-11-19) to not
consider only the last output. We need to know if any output is
SYMBOLIC, so stop checking as soon as one is found.
Since commit v3.5.0-rc1~241^2~1 (cmFortranParser: Parse #line
directives, 2015-11-02) our Fortran dependency scanner parses `#line`
directives to extract the named files. However, some compilers produce
`#line` directives that name directories instead of files. Work around
such cases by verifying that the extracted path names a file and not a
directory.

Rename methods:

* `cmLocalGenerator::Find{ => LocalNonAlias}GeneratorTarget`
These names clarify that they are for directory-local target names
and do not consider alias targets.
Refactoring in commit v3.5.0-rc1~272^2~11 (cmTarget: Implement ALIAS in
terms of name mapping, 2015-10-25) accidentally introduced logic that
assumes ALIAS targets always reference targets in their own directory.
Fix this and add a test case.
The configure-step fix is that `cmMakefile::FindTarget` should not consider
aliases. The purpose of this method is just to look up targets local to
a directory. Since ALIAS and normal targets share a namespace we know a
locally defined target will never collide with an ALIAS target anyway.
The method has 3 call sites, and this change is safe for all of them:
* `cmInstallCommand::HandleTargetsMode`: Rejects aliases before the call.
* `cmFLTKWrapUICommand::FinalPass`: Should never have considered aliases.
* `cmMakefile::FindTargetToUse`: Falls back to a global lookup anyway.
The generate-step fix is that `cmLocalGenerator::FindGeneratorTarget`
should not consider aliases. This method is the generate-step
equivalent to the above. The method has 2 call sites, and this change
is safe for both of them:
* `cmInstallTargetGenerator::Compute`: Never uses an alias target name.
* `cmLocalGenerator::FindGeneratorTargetToUse`: Falls back to global lookup.

path runs on every condition (e.g. `if()`) and so the path conversion
has a noticeable performance cost. Fortunately the only use of this
context is for insertion into cmMakefile::CMP0054ReportedIds so we do
not need to convert the path. Simply drop the conversion.

Re-lookup a variable value when an associated VariableWatch is executed
in cmMakefile::GetDefinition.
This fixes a problem with 'def' sometimes becoming invalid due to memory
reallocation inside an std::vector. In this case, the problem was that
if the call to VariableAccessed actually executed a callback function,
the internal state of the makefile has changed due to the associated
function scope being pushed. This in turn implies that a new
cmDefinitions instance was pushed in cmMakefile::VarTree. As
cmLinkedTree is based on an std::vector, this push can have triggered
reallocation of its internal memory buffer. However, as the value of
'def', which was computed on method entry, actually points to a property
of one of the cmDefinitions instances in cmMakefile::VarTree,
reallocation can invalidate the value of 'def' so that it cannot simply
be returned at the end of the function. The solution implemented here is
to simply lookup the value of 'def' again.
This commit fixes a bug in the implementation of the test property
TIMEOUT_AFTER_MATCH. The new timeout value was being applied
every time a line was output by the test after the match had been

property.

Some compilers on OS X report errors in the CoreServices framework headers.
Check for support of the header ahead of time and compile the relevant code
only when the header is available.
With the Makefile generator one can use `cd $subdir; make all` to build
all targets associated with a given subdirectory. This is not possible
to do with the Ninja generator since there is only one `build.ninja`
file at the top of the build tree. However, we can approximate it by
allowing one to run `ninja $subdir/all` at the top of the tree to build
the targets in the corresponding subdirectory.

In commit v3.5.0-rc1~43^2 (Fix export of STATIC library PRIVATE
dependencies with CMP0022 NEW, 2016-01-15) we taught
target_link_libraries to generate `$<LINK_ONLY:$<TARGET_NAME:dep>>` in
INTERFACE_LINK_LIBRARIES instead of `$<LINK_ONLY:dep>` so that `dep` can
be recognized as a target name and updated during export. However, this
approach does not work when `dep` is just a plain library name and not a
target because `$<TARGET_NAME:...>` requires the name of a reachable
target.
Since we do not know during target_link_libraries whether the name will
correspond to a reachable target or not, we cannot inject the
`$<TARGET_NAME:...>` expression. Revert this change and solve the
original problem instead by teaching the export logic to recognize and
update target names directly in `$<LINK_ONLY:...>` expressions.

Refactoring in commit v3.3.0-rc1~29^2~1 (cmState: Host some state from
the cmGlobalGenerator, 2015-05-24) moved storage of some generator
traits over to cmState. However, it accidentally removed initialization
of the values from the cmGlobalGenerator constructor. This is needed
because generator subclasses update the settings in their constructors.
Since a single cmState instance is shared across multiple build trees by
cmake-gui, initializing the values in its constructor is not enough.
Fix this by restoring the needed initializations to the
cmGlobalGenerator constructor.
We represent target dependency sets as `set<cmTargetDepend>` which
orders by a `cmGeneratorTarget const*` pointer value. Therefore the
order of dependencies encountered in AppendTargetDepends is not
predictable. Sort them by content to make the result deterministic.

source files specifying them. Do not depend on pointer values of
internally allocated structures for ordering.

Let us take an example of a project that has some tests in a component
that need to be installed into a dedicated test package. The user
expectation is that the result could be achieved by typing the
following:
make
make tests
make install
DESTDIR=/testpkgs make install-tests
However this results in test components in the default installation as
well as the testpkg.
Add an EXCLUDE_FROM_ALL option to the install() command to tell it that
the installation rule should not be included unless its component is
explicitly specified for installation.
While evaluating `if(MATCHES)` we get a `const char*` pointer to the
string to be matched. On code like
if(CMAKE_MATCH_COUNT MATCHES "Y")
the string to be matched may be owned by our own result variables.
We must move the value to our own buffer before clearing them.
Otherwise we risk reading freed storage.
The add_custom_command(TARGET) signature only works for targets defined
in the current directory. Clarify this in the error message when the
target exists but was defined elsewhere.

Since commit v3.4.0-rc1~5^2~1 (VS: Add support for selecting the Windows
10 SDK, 2015-09-30) the VS 2015 generator requires a Windows 10 SDK to

building on a Windows 10 host). Howewver, it is possible to install VS
2015 without any Windows 10 SDK. Instead of failing with an error
message about the lack of a Windows 10 SDK, simply tolerate this case
and use the default Windows 8.1 SDK. Since building for Windows Store
still requires the SDK, retain the diagnostic in that case.

We can remove the temporary allocations required for the

Some compilers may add their own RPATH entries when invoking the linker.
For example, a GCC installation may contain the following definition in
the specs file:
*link_libgcc:
%D -rpath <<some specific rpath in which libstdc++.so can be found>>
In this case binaries may contain RPATH entries that CMake did not add.
When we update the RPATH on installation we must preserve these entries
even if CMake thinks the INSTALL_RPATH value should be empty.
Fix this by always using file(RPATH_CHANGE) and teach it to behave as
file(RPATH_REMOVE) if the actual RPATH in the file is empty after
replacing the build-tree RPATH with the install-tree RPATH. This will
preserve any compiler-added RPATH value instead of removing it.
The target_link_libraries command records the PRIVATE dependencies of a
STATIC library in INTERFACE_LINK_LIBRARIES as "$<LINK_ONLY:dep>". This
hides the target name from export namespacing logic inside a generator
expression. When user-written generator expressions reference a target
name they must put it inside a "$<TARGET_NAME:dep>" expression to allow
the export logic to rename the target. In the case that the private
dependency is not already a generator expression, target_link_libraries
must use "$<LINK_ONLY:$<TARGET_NAME:dep>>" to allow the export logic to
rename the target.

4ca9df8b cmIDEOptions: Add support for case-insensitive flags
In commit v3.4.0-rc1~5^2~1 (VS: Add support for selecting the Windows 10
SDK, 2015-09-30) we added Windows 10 SDK selection choosing the most
recent SDK that is not newer than the target version. This is backward
because it should be up to the application code to not use APIs newer
than the target version. It is up to the build system to provide a SDK
that has at least the APIs expected to be available for the target
version. Furthermore, since the default target version is the host
version of Windows, the old approach breaks when the only SDK available
is for a newer version of Windows.
Fix this by always selecting a Windows 10 SDK if one exists. Use the
SDK for the exact version if is available. Otherwise use the latest
version of the SDK available because that will have at least the APIs
expected for the target version.
Fix the link flag table entries for this flag to be case-insensitive.
Also fix the VS 2015 value for the build property enumeration name.
This causes `linkOptions.Parse(...)` to correctly extract the `/debug`
flag and map it to the IDE property instead. Therefore we do not need
to look for the flag explicitly when initializing the property.
Starting with VS 2015 the GenerateDebugInformation build property is an
enumeration (`No`, `Debug`, `DebugFastLink`) instead of a boolean value
(`false`, `true`). For now we simply change to `No` and `Debug` fix
current behavior. Support for `/debug:fastlink` can be added later.
