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.
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 Custom-Symbolic-and-Byproduct case fails strangely on some
filesystems used by our nightly testing. Somehow on the first build the
`use-byproduct` output ends up with a timestamp older than
`gen-byproduct-stamp` even though the build log clearly shows them build
in the correct order (and must according to build system dependencies).
Work around this problem by adding an extra delay before building
`use-byproduct`.

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.

The fix in commit v3.5.0-rc1~27^2 (FindPkgConfig: set standard variables
in the cache, 2016-01-20) added the wrong variable name to the cache.
The test was only testing that the cache variable existed, not that it
also had the correct value. Update the test to ensure that the cache
value matches the local variable value.

If list of valid target architectures is empty for given SDK then there will
be no VALID_ARCHS build setting returned by Xcode. Return "" (empty string)
explicitly in this case. This may happens if CMAKE_IOS_INSTALL_COMBINED is ON
but only one architecture used in target.
Calling `project()` or `enable_language()` from a toolchain file will
infinitely recurse since those commands load the toolchain file.
Diagnose and reject this case with an error message instead of crashing
when the stack eventually overflows.
Although we fail with an error on a hash mismatch, it is not a fatal
error so the script may continue processing. If the download itself had
no error then report in the STATUS variable that the operation was not
successful due to the hash mismatch.

Create a `CMAKE_TRY_COMPILE_TARGET_TYPE` option to specify use
of `add_library(... STATIC ...)` for the generated test project.
This will be useful for cross-compiling toolchains that cannot
link a binary without custom flags or scripts.
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.

CPACK_* variables expect component name in upper case.
CPACK_RPM_* variables expected component name to be
in same case as component name.
This patch adds support for CPACK_RPM_* variables with
upper case component names to match the convention with
CPACK_* variables and also preserves same case component
names for back compatibility.
The re-implementation in commit v3.5.0-rc1~116^2~1 (CMakeParseArguments:
replace by native cmake_parse_arguments command, 2015-12-05) introduced
a regression when parsing the ARGN arguments with cmake_parse_arguments.
The original implementation used
foreach(currentArg ${ARGN})
to iterate over input arguments. This flattened ;-lists within the
arguments whether they were quoted or not. Fix our new implementation
to preserve this behavior and add a test case to cover it.

47460f3e install(EXPORT): Fix crash on target in another directory
e86383e1 Tests: Use newer policy settings in RunCMake.install test
The EXPORT-OldIFace test case uses install(TARGETS) and so generates a
warning:
CMake Warning in CMakeLists.txt:
WARNING: Target "foo" has runtime paths which cannot be changed during
install. To change runtime paths, OS X version 10.6 or newer is required.
Therefore, runtime paths will not be changed when installing.
CMAKE_BUILD_WITH_INSTALL_RPATH may be used to work around this limitation.
Set CMAKE_BUILD_WITH_INSTALL_RPATH to avoid the warning since we do not
need to run the binaries from the build tree anyway.
Previously we did not clearly document that `--target` is only supported
to be specified once. Even worse, specifying it multiple times would
silently ignore any previously specified targets and only build the last
target.
Update the documentation to specify this. Update the implementation to
reject multiple `--target` options to prevent user errors.
Refactoring merged by commit v3.5.0-rc1~299 (Merge topic
'use-generator-target', 2015-10-20) in and around
commit v3.5.0-rc1~299^2~13 (cmExportSet: Store a cmGeneratorTarget,
2015-10-17) changed export sets to delay looking up actual targets and
stores only their names. However, in InstallCommand::HandleExportMode
we need to lookup targets immediately to check them for
EXPORT_LINK_INTERFACE_LIBRARIES. The check was accidentally made local
to the current directory, so if an export set contains a target from
another directory the lookup fails and CMake crashes. Fix the check to
look up the target name globally, and tolerate when no target is found
just in case.

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.

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.
The behaviour of double specified keywords is rather undefined or at
least not clearly documented. This change introduces a strict check and
emits a warning in case a keyword has been specified more than once.
Implement a native `cmake_parse_arguments` command that is fully
compatible with the documented behaviour of the previous implementation.
Leave the CMakeParseArguments module empty but existing for
compatibility.
This patch solves the problem of installing both: Device and Simulator
libraries on iOS. Before only one of them was installed.
If the IOS_INSTALL_COMBINED property is set on a target, a
special install hook will be activated which builds the corresponding
target and combines both at the install location.
The original patch was contributed by Ruslan Baratov, and polished by
Gregor Jasny.
If multiple input files are provided then the destination must be a
directory. If only one input file is provided then destination may be
either a file or directory.
A typical iOS application bundle (also Framework Bundle) contains the
application executable and any resources used by the application (for
instance, the application icon, other images, and localized content) in
the top-level bundle directory. The same rule applies to Framework
Bundles.
Explicitly enable deprecated warnings by default, via the

Make the message suppression more consistent, by adding a check
for the message related CMake variables in cmake::IssueMessage,
which allows callers of IssueMessage other than the message

CMAKE_SUPPRESS_DEVELOPER_WARNINGS in the message command to
mirror the deprecated message type behaviour.
Added a 'force' flag to the cmake::IssueMessage method, to
make the message suppression consistent, when setting the
message related CMake variables directly in a CMake file.
Expand message command tests to cover the AUTHOR_WARNING message
type as well.
This fixes a bug where 64 bit builds with /bigobj incorrectly determined
that the object files were not 64 bit. This manifested itself with
printf type functions showing up as undefined because the leading
underscore was being removed and should not be removed.
If a custom command has a SYMBOLIC output (that is never actually
created) then do not mark the custom command build statement as
'restat'. Otherwise other custom commands that depend on the symbolic
output may not always re-run because after running the first custom
command Ninja 'restat' will detect that the output timestamp did not
change and skip its dependents.
This was observed with the ExternalProject BUILD_ALWAYS option where
Ninja would not re-run the 'install' step each time 'build' re-runs.
