The libarchive APIs use nl_langinfo(CODESET) for iconv so they need the
locale to be set for LC_CTYPE. However, the rest of CMake does not
define any behavior for non-ASCII character classification/conversion so
we do not want to setlocale() globally. Add a RAII class to save, set,
and restore the locale around calls to libarchive APIs.

Revert the changes made by commit v3.1.0-rc1~406^2~1 (Encoding: Add
setlocale() to applications, 2014-05-30) and commit v3.1.0-rc1~406^2
(Encoding: Change to only set LC_CTYPE, 2014-06-11), and other setlocale
calls added later in their spirit. CMake has not been taught how to
deal with non-C locales everywhere. We do not define any functionality
for character conversions for non-ASCII strings. Another solution will
be needed to address the original problem motivating addition of
setlocale() calls.
Replace use of separate "cmake -E cmake_progress_report" and "cmake -E
cmake_echo_color" commands to report the progress and message portions
of build output lines with --progress-* options to the latter to print
everything with a single command. The line buffering of the stdout FILE
stream should cause the whole line to be printed with one atomic write.
This will avoid inter-mixing of line-wise messages from different
processes during a parallel build.
The CMAKE_<LANG>_STANDARD_DEFAULT variable indicates whether the
compiler has any notion of standard levels and that CMake knows
about them. If no language standard levels are available, skip
all logic to attempt to add a flag for the level.

In commit v3.0.0-rc1~222^2 (Makefile: Allow "gmake target1 target2 -j",
2013-12-18) we added generation of a .NOTPARALLEL rule and told the
generator it is "symbolic" because the file will never be created.
This causes ".PHONY" to be used. However, "clearmake" does not support
parsing of .PHONY specifically for .NOTPARALLEL, so simply drop it.
This should not affect the role of the .NOTPARALLEL rule for GNU make.
The "/showIncludes" flag is only available with MS C and C++ compilers,
and on compilers that "simulate" them (like Intel for Windows). Fix our
logic to choose this type only for MS tools with these languages. All
other cases need to use "deps = gcc" and define DEP_FILE in the build
rule.
Define an empty string in CMAKE_<LANG>_STANDARD_DEFAULT to mean that
the toolchain has no notion of lanuage standard levels. In this case
the <LANG>_STANDARD[_REQUIRED] properties will have no effect.
Update the RunCMake.CompileFeatures test to exclude the
LinkImplementationFeatureCycle test when there is no standard default.
It can never fail because no use of specific features will adjust the
CXX_STANDARD level required for any target since the standard levels
have no meaning in this case.

This causes the line to contain newlines and possibly be cut off in the
middle of a line. Fix this regression by restoring use of the proper
end-of-line position.
Case where CPACK_CMAKE_GENERATOR value is non existent or

creates typedefs with custom comparison functors etc, which
can not use this algorithm.
Commit v3.1.0-rc1~297^2~5 (cmTarget: Drop 'head' argument from
GetSourceFiles, 2014-07-10) exposed a dormant bug in source file computation,
causing the test case to regress. After that commit, the source file
computation and caching finds an existing container of source files. Prior to
that patch, the GetSourceFiles method was called with either a null pointer
for the head cmTarget, or it was called with the this pointer. The
processSources method is eventually called, which normalizes the difference
between the null pointer and the this pointer for the head target. However,
the cache key depends on the actual pre-normalized pointer. The change in
that commit caused the entry to be found in the cache where it was not before,
which resulted in incorrect behavior.
Prior to that commit, the test case also fails if the GetSourceFiles overload
taking a vector<cmSourceFile*> is changed to normalize the head target at
the beginning of the method:
cmTarget const* head = head_ ? head_ : this;
Such a construct was correctly used in other locations where similar caching
was in place, before being removed in commit v3.1.0-rc1~310^2~25 (cmTarget:
Remove 'head' argument from GetLinkInformation, 2014-06-12), but is not
neccessary anymore.
Commit v3.1.0-rc1~674^2~2 (cmTarget: Cache the cmSourceFiles in
GetSourceFiles., 2014-04-05) introduced the caching, but fails the test case
for an unrelated reason. That unrelated error was introduced in
commit v3.1.0-rc1~688^2~5 (cmTarget: Allow any generator expression in
SOURCES property., 2014-03-18) and fixed in
commit v3.1.0-rc1~561^2~1 (cmTarget: Fix listing of source files at
configure-time., 2014-04-13).
All commits which fail the test case in the testable way do so when such a
cached version of the source files is found and returned at generate
time. In the test case, the cached content is populated at configure-time
through the use of the deprecated LOCATION property with CMP0026 OLD. The
cached content is an empty container for the bar target in the test case,
because its source file 'foo.cpp.o' is not known until generate-time. That
means that no source files are available to compute the link language and
the reported error is issued.
The actual problem is that the SourceFilesMap should be cleared after
configure time by cmTarget::ClearLinkMaps. Clear it there now.

Refactoring in commit v3.1.0-rc1~688^2~2 (cmTarget: Compute languages
from object libraries on demand, 2014-03-18) taught cmTarget::GetLanguages
to (correctly) include the languages of object library sources. Previously
this was done only in cmTarget::ComputeLinkImplementationLanguages to
choose the linker language.
The Ninja generator writes out generic build rules for each language
compiled within a target using the rule variables defined in the
directory of the target. This only needs to be done for languages
actually compiled within the current target. Switch from using the
cmTarget::GetLanguages method to get the list of languages over to
using cmTarget::GetSourceFiles directly so we do not get the languages
in object libraries.
Strictly speaking this should make no difference because it is not safe
to use objects from a language not enabled in the directory containing
a target or else the link information for the language may not be
considered. However, in cases when no link information happens to be
needed for a language it was possible in CMake 3.0 and below to enable
a language only in a subdirectory providing an object library, and then
use the objects from a containing directory. The above change teaches
the Ninja generator to continue working in this case.

When install(EXPORT) is given an absolute destination we cannot compute
the install prefix relative to the installed export file location.
Previously we disallowed installation of targets in such exports with a
relative destination, but did not enforce this for target property
values besides the location of the main target file. This could lead to
broken installations when the EXPORT is installed to an absolute path
but usage requirements are specified relative to the install prefix.
Since an EXPORT installed to an absolute destination cannot be relocated
we can just hard-code the value of CMAKE_INSTALL_PREFIX as the base for
relative paths. This will allow absolute install(EXPORT) destinations
to work with relative destinations for targets and usage requirements.
Extend the ExportImport test with a case covering this behavior.
A few pieces of code have some ambiguous type deduction that seems to
resolve correctly for most compilers but not for the Oracle compiler.
This makes those few instances more explicit.
In the unlikely event that someone has a billion+ scripts (or some
codepath returns negative numbers), we could overflow and make a pile of
errors a non-error. This change also allows us to use flags for the
error in the future rather than just "something went wrong".
We use cmGlobalGenerator::GetDirectoryContent to avoid repeating
directory listings. However, GetDirectoryContent loads content from
disk at most once. This breaks find_library calls that occur when disk
content has changed since preceding find_library calls.

modification time when content is loaded and re-load content if it
changes.

If a source file COMPILE_FLAGS option adds "-wd", the .vcxproj file

Add to the setting a reference to %(DisableSpecificWarnings) to

Copy CMAKE_EXE_LINKER_FLAGS into the test project generated by

When compiling the ABI detection test project, do not override
CMAKE_EXE_LINKER_FLAGS completely. The normally selected value of this
variable may influence how the link is done and may be needed to be
representative of how the calling project will be built. Instead pass a
variable that try_compile will reference as additional flags. Leave
this behavior of try_compile undocumented for now.
With PushScope and PopScope, keeping track of another bit of data for
each scope isn't easy. Instead, store it as another CMake variable so it

Since commit v3.1.0-rc1~821^2 (Windows: Use response files to specify
link libraries for GNU tools, 2014-03-04) we use a response file to pass
possibly long linker flag lists to the GNU linker on Windows. On MinGW,
this may cause gfortran to use a response file to pass some flags to its
own internal invocation. This is okay except when we are parsing
implicit link flags from the compiler ABI detection build. If gfortran
uses a response file in that case then we may miss extracting some of
the implicit link flags, such as -lgfortran. Fortunately, in the
compiler ABI detection case we do not actually link to anything so the
response file is empty. Work around this problem by simply not using a
response file when the list of flags it is used to pass is empty (or
just whitespace).

7d674b5f Revert "ClearMatches: Only clear matches which were actually set" (#15261)
This can be allowed in the next release, but it needs to have some
features present and tested such as
* Ensuring that relative paths do not appear in the generated property.
* Ensuring that paths to the source or build directories do not appear.
* Generating a check in the file for CMake 3.1 or later so that the
resulting property will be consumed.
* Ensuring that any referenced targets are part of an export set and
generating a check for them.
* INSTALL_INTERFACE and BUILD_INTERFACE content.
All of these checks are already done for INTERFACE_INCLUDE_DIRECTORIES,
but it is too late to add them for INTERFACE_SOURCES for CMake 3.1.
As the checks introduce some new error conditions, it is better to
disallow exporting fully for this case and introduce proper error
conditions later instead of policies.
Follow the pattern of checks that are made for INTERFACE_INCLUDE_DIRECTORIES.
Existence is already checked by cmSourceFile::GetFullPath. Add a check
to disallow relative paths in source directories. Otherwise code such as
target_sources(lib1 INTERFACE foo.cpp)
would fail if consumed by a target in a different directory.
Unlike the INTERFACE_INCLUDE_DIRECTORIES behavior, we don't care whether
the entry comes from an IMPORTED target or not. In the include directories
case, the directory for a non-imported target might not exist yet but
might be created. In the sources case, a file which does not yet
exist in the filesystem must be explicitly marked with the GENERATED
property.
Adjust existing tests and add a new test for the error.
Since commit v3.1.0-rc1~688^2~15 (cmTarget: Add a method to obtain list of
filenames for sources, 2014-03-17) we have code paths that lookup sources by
strings containing their own full path after normalization to the actual case
on disk. This fails in the case that a cmSourceFile has already been created
with a different case in the filename. The comparison of the directory works
because it is always normalized. Only the comparison of the file name fails.
Fix this by using a case-insensitive comparison of source file names on
platforms that do not have case-sensitive filesystems.
Extract a new method to encapsulate the requirements of evaluating
dependent-expressions, namely, propagation of the
EvaluateForBuildsystem setting, which is missing from the
getLinkedTargetsContent implementation.
Commit v3.1.0-rc1~688^2 (Genex: Only evaluate TARGET_OBJECTS to determine
target sources., 2014-03-20) introduced an error case for use of
TARGET_OBJECTS outside of the context of generating the buildsystem,
as the path to object files may be dependent on buildsystem
variables (See bug #15226).
Commit v3.1.0-rc1~314^2 (Allow INTERFACE_SOURCES to specify
$<TARGET_OBJECTS> (#14970), 2014-07-09) made it possible to
propagate such content to dependent targets.
While that commit propagated the EvaluateForBuildsystem setting
for the case of a TARGET_PROPERTY expression, as generated for
direct dependencies of a target in
cmTargetInternals::AddInterfaceEntries, it did not add propagation
for content from further transitive target dependencies, as determined
by getLinkedTargetsContent.
This reverts commit v3.1.0-rc1~557^2~2 (ClearMatches: Only clear matches
which were actually set, 2014-03-12). The optimization did not track
the match count in the same scope as the variables, allowing possible
inconsistency.

It gets incremented while entering a loop block (e.g. foreach or while)
and gets decremented when leaving the block. Because scope borders for
example at function borders must be taken into account the counter is
put into a stack. With every new scope an empty counter is pushed on the
stack, when leaving the scope the original value is restored.
This will allow easy querying if the break command is properly nested
within a loop scope.

This commit fixes a bug where it was impossible to specify
/INCREMENTAL to Fortran projects built with Visual Studio.
The problem was due to the fact that .vfproj files expect
the value of this flag to be "linkIncremental{No,Yes},
whereas .vcproj files expect this value to be 0, 1, or 2.
The implementation of this fix adds a new data structure for
Visual Studio linker flags specific to Fortran. This can
easily be extended in the future if more such discrepencies
between C/C++ and Fortran linking are discovered.
Re-run if the input file changes or if the output file is removed.
This only works with the Makefile generators currently. The limitation
of the Ninja generator is tracked as issue #15256. The IDE
generators will need larger refactoring as they currently rely on
being able to determine the depends and output files at the start of
generate-time, which is too early for the file(GENERATE) case.

A common idiom in CMake-based build systems is to have custom commands
that generate files not listed explicitly as outputs so that these
files do not have to be newer than the inputs. The file modification
times of such "byproducts" are updated only when their content changes.
Then other build rules can depend on the byproducts explicitly so that
their dependents rebuild when the content of the original byproducts
really does change.
This "undeclared byproduct" approach is necessary for Makefile, VS, and
Xcode build tools because if a byproduct were listed as an output of a
rule then the rule would always rerun when the input is newer than the
byproduct but the byproduct may never be updated.
Ninja solves this problem by offering a 'restat' feature to check
whether an output was really modified after running a rule and tracking
the fact that it is up to date separately from its timestamp. However,
Ninja also stats all dependencies up front and will only restat files
that are listed as outputs of rules with the 'restat' option enabled.
Therefore an undeclared byproduct that does not exist at the start of
the build will be considered missing and the build will fail even if
other dependencies would cause the byproduct to be available before its
dependents build.
CMake works around this limitation by adding 'phony' build rules for
custom command dependencies in the build tree that do not have any
explicit specification of what produces them. This is not optimal
because it prevents Ninja from reporting an error when an input to a
rule really is missing. A better approach is to allow projects to
explicitly specify the byproducts of their custom commands so that no
phony rules are needed for them. In order to work with the non-Ninja
generators, the byproducts must be known separately from the outputs.
Add a new "BYPRODUCTS" option to the add_custom_command and
add_custom_target commands to specify byproducts explicitly. Teach the
Ninja generator to specify byproducts as outputs of the custom commands.
In the case of POST_BUILD, PRE_LINK, and PRE_BUILD events on targets
that link, the byproducts must be specified as outputs of the link rule
that runs the commands. Activate 'restat' for such rules so that Ninja
knows it needs to check the byproducts, but not for link rules that have
no byproducts.
Use an explicit "$TARGET_FILE" variable instead of "$out" so that
we can have multiple output files while still only referencing the
main one in command lines.
Now that we know the year component of this VS version we
can add it to the generator name. For convenience, map
the name without the year to the name with the year.
Visual Studio 14 (2015) complains if a static character array is
declared with more than 65535 elements. This limit should be large
enough for SharedForward clients, so just hard-code that instead of
trying to compute a limit.
Teach the add_custom_command and add_custom_target commands a new
USES_TERMINAL option. Use it to tell the generator to give the command
direct access to the terminal if possible.
CMake requires both the Desktop SDK and the correct platform SDK
(Windows Phone or Windows Store) to be installed when targeting the
Windows mobile platforms. Verify that the right platform components are
installed and give a more detailed error message when something is
wrong.
string SUBSTRING command now ignores length if it points
past end of string and uses end of string instead.
String SUBSTRING tests now cover more corner cases.
