Calls to `IsKeyword("...")` cause runtime construction of std::string.
Avoid possible repeated allocation by pre-allocating keyword strings
during initialization.
In commit v3.4.0-rc2~1^2 (cmIfCommand: Issue CMP0054 warning with
appropriate context, 2015-10-20) we added construction of a
cmListFileContext with conversion of the calling file path. This code
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
encountered. Now the new timeout value is only set once.

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

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.
There were issues in the special-character-escaping and line-wrapping
code which caused DragNDrop packaging to fail mysteriously at a later
step with parsing errors in the `sla.r` file generated by the following
code.

Before this change backslashes in strings were escaped during compile
flags adds via AppendFlag(). But global flags like OTHER_CPLUSPLUSFLAGS
are not added as flags but as plain strings so they were not escaped
properly.
Now the escaping is performed within cmXCodeObject::PrintString() which
ensures that strings are always encoded.
