Since jsoncpp 0.7.0 (2014-11-20) the upstream may provide a CMake
package configuration file such that find_package(jsoncpp) will find a
jsoncppConfig.cmake file. In order to avoid conflicting with this
(especially on case-insensitive filesystems), and since we always prefer
projects to provide package config files (that they maintain), it is
better to not provide FindJsonCpp publicly.
Move FindJsonCpp into a private source directory that is not installed
so that we can still use it for building CMake itself.

Pre-C++98 compilers required that the template argument be
used in the function parameters. Those compilers are no longer
supported as hosts, so drop the workaround.
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.
The command has been documented as 'deprecated', but it is not really
slated for removal and can still be used. Clarify this in the
documentation. While at it, revise the documentation to use wording
more consistent with that now in target_link_libraries.

Provide a function to run gcov and create a tarball of results.
Since CDash tracks the md5sum of the files uploaded, use the
--mtime option with "cmake -E tar" so that tar files could be
created that would have the same md5sum with the same content.
This fixes several reported bugs about CMake not handling
non-ascii paths on Windows.
Practically, the use of some unicode characters may still
be limited by the build or compiler tools.
For example, a user may be limited by the build tools to
using characters within the Windows ANSI code page (which can
include non-ascii characters in the current system language).
Also add a 'CMAKE_ANDROID_API_MIN' variable to set the property
default. Teach the VS generator to write the MIN API value into
Nsight Tegra project files.
The use of FeatureSummary inside a find module is not a convention
yet used by upstream CMake modules. Drop the example from the
documentation about how to write find modules. If in the future
we add use of FeatureSummary to many of the upstream find modules
then this example can be restored as part of establishing the
convention.

An IMPORTED target in either type of package can equally depend on
an IMPORTED target in a Find module, which must be found as a
dependency, which is presumably the problem being implied. This is
not a distinction of creating an IMPORTED target in a Find module.
The FindXerces module was added in commit v3.1.0-rc1~155^2 (FindXerces:
New module to find Apache Xerces-C++, 2014-08-17). However, there are
two implementations of Xerces, one in C++:
http://xerces.apache.org/xerces-c/
and one in Java:
http://xerces.apache.org/xerces-j/
Rename FindXerces to FindXercesC to clarify that it is about the C++
implementation.
While at it, add the missing CMake 3.1 release note about this module.

Copy CMAKE_EXE_LINKER_FLAGS into the test project generated by
try_compile, just like we already copy CMAKE_<LANG>_FLAGS.
Add CMake Policy CMP0056 to activate this behavior in a compatible way,
but do not warn by default when the policy is not set since it will
affect all try_compile calls.
Extend the RunCMake.try_compile test with a case covering this behavior
for each policy setting.
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
gets implicitly tracked along with everything else.
This works in a revert of commit
7d674b5f0b.
Add a VS_DEPLOYMENT_LOCATION source file property to specify where to
put files that are part of the package. For example:
set_property(SOURCE ${ASSET_FILES} PROPERTY VS_DEPLOYMENT_LOCATION "assets")
Without this, sources marked with VS_DEPLOYMENT_CONTENT cannot be
located properly.
Create properties VS_SHADER_ENTRYPOINT and VS_SHADER_MODEL. Without
these many .hlsl source files may not be possible to use. Extend the
VSWinStorePhone test project to cover them.
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.
Add support for Sun/Uniforum/GNU gettext libintl. This belongs in CMake
rather than upstream because:
* There are multiple upstreams (Sun, GNU).
* It may or may not be in the glibc C library depending
upon the platform and build options used.
Although we already have a FindGettext module, that is for the tools.
This module is for the library, and is independent because it's
perfectly OK to use libintl without the gettext tools (and vice versa),
and they might not all be found. Add cross references between the two
modules in notes to make the relationship clearer.

Define the 'cmake -A' option to set CMAKE_GENERATOR_PLATFORM
without having to spell out the whole variable name. We choose
the name '-A' for "platform" because '-P' is already taken, and
in the common use case the "platform" is actually an architecture
(e.g. x64).
Teach the RunCMake test infrastructure to use -A to pass the generator
platform. Extend the RunCMake.GeneratorPlatform test with a case to
verify that the -A option cannot be repeated.
The ctest_configure command already reads the CTEST_CMAKE_GENERATOR
variable to get the value for the cmake -G option. Read new variable
CTEST_CMAKE_GENERATOR_PLATFORM to pass on as CMAKE_GENERATOR_PLATFORM.
The "ctest --build-and-test" mode already has "--build-generator" to
specify the -G option to CMake. Add a "--build-generator-platform" option
to specify a value to pass on as CMAKE_GENERATOR_PLATFORM.
Reject the option by default. It will be implemented on a per-generator
basis. Pass the setting into try_compile project generation. Add cache
entry CMAKE_GENERATOR_PLATFORM and associated variable documentation to
hold the value persistently.
Add a RunCMake.GeneratorPlatform test to cover basic use cases for the
option. Verify that CMAKE_GENERATOR_PLATFORM is empty by default, and
that it is rejected when the generator does not support a user setting.

Explicitly specify the sequence of underline characters we use in the

Update a few places where we were using other characters.
Explain how to use $<BUILD_INTERFACE> and $<INSTALL_INTERFACE> directly
in the documentation of the target_include_directories command and
INTERFACE_INCLUDE_DIRECTORIES target property. Otherwise readers need

example in that to understand the need for these expressions.
Also fix the explanation in cmake-buildsystem(7) to not claim that
relative paths may be used inside a BUILD_INTERFACE expression.
Teach set_property and get_property an "INSTALL" property type to be

Extend the cmake-developer(7) documentation with notes on
extending feature support for compilers.
Allow setting build properties based on the features available
for a target. The availability of features is determined at
generate-time by evaluating the link implementation.
Ensure that the <LANG>_STANDARD determined while evaluating
COMPILE_FEATURES in the link implementation is not lower than that
provided by the INTERFACE of the link implementation. This is
similar to handling of transitive properties such as
POSITION_INDEPENDENT_CODE.

* CMAKE_EXPORT_NO_PACKAGE_REGISTRY that disables the export(PACKAGE)

Allow directories in the source tree or build tree only if the
install tree is a subdirectory of the source tree or build tree,
as appropriate.
Re-use the test files in the RunCMake.include_directories test
to run in multiple scenarios. Bump the required CMake version
in the test to 3.0 to ensure that the new policy warnings are
emitted correctly.
This can be used to set the compiler features required by particular
targets. An error is issued at CMake time if the compiler does not
support the required feature. If a language dialect flag is required
by the features used, that will be added automatically.
Base the target_compile_features command on cmTargetPropCommandBase. This
gives us 'free' handling of IMPORTED, ALIAS, INTERFACE, non-compilable
and missing targets.
Extend the interface of the target_compile_features command with
PUBLIC and INTERFACE keywords. Populate the INTERFACE_COMPILER_FEATURES
target property if they are set. Consume the INTERFACE_COMPILER_FEATURES
target property from linked dependent targets to determine the final
required compiler features and the compile flag, if needed.
Use the same pattern of origin-debugging which is used for other
build properties.
Use the contents of it to upgrade the CXX_STANDARD target property,
if appropriate. This will have the effect of adding the -std=c++11
compile flag or other language specification on GNU when that is
needed for the feature.
Add a feature test using the compiler macros and the preprocessor to
determine available features.
Add a CMAKE_CXX_COMPILE_FEATURES variable which contains all features
known to the loaded compiler, and a CMAKE_CXX_KNOWN_FEATURES variable
containing all features known to CMake. Add language standard specific
variables for internal use to determine the standard-specific compile
flags to use.
This will be extended to other languages in the future. Follow-up
commits will add features which will be recorded by the feature test.

Extend the cmGeneratorExpressionDAGChecker with an interface
returning the name of the top target. Use that to determine
when there is a DAG violation, as required by the RunCMake.Languages
tests.
The output of this expression may contain macros for IDEs to replace
such as $(Configuration), $(CURRENT_ARCH) etc. To avoid generating
content which is not usable in other contexts, report an error if
there is an attempt to use it in other contexts.
This commit may be reverted in the future if a solution to the
above difference is implemented.
These policies are triggered by the use of a particular compiler rather
than outdated CMake code in a project. Avoid warning in every project
that enables a language by not displaying the policy warning by default.
Add variable CMAKE_POLICY_WARNING_CMP<NNNN> to control the warning
explicitly; otherwise enable the warning with --debug-output or --trace.
This breaks with strict policy convention because it does not provide
developers with any warning about the behavior change by default.
Existing projects will continue to build without a warning or change in
behavior. When a developer changes the minimum required version of
CMake in a project to a sufficiently high value (3.0), the project will
suddenly get the new compiler id and may break, but at least the
breakage comes with a change to the project rather than the version of
CMake used to build it.
Breaking strict policy convention is worthwhile in this case because
very few projects will be affected by the behavior change but every
project would have to see the warning if it were enabled by default.
As well as the traditional variables, providing imported targets is
suggested, and the relative advantages and disadvantages briefly
discussed.
A mini-tutorial walking through creating a simple find module is
provided.
This changes the recommended version variable from Foo_VERSION_STRING to
Foo_VERSION, because there is really no need to have different variable
names for package version files vs. find modules. It notes the old
variable name, though, and suggests setting it for compatibility.
Since commit v2.8.12~437^2~2 (VS: Separate compiler and linker PDB files
2013-04-05) we no longer set /Fd with the PDB_NAME or PDB_OUTPUT_DIRECTORY
properties. Those properties now exclusively handle linker PDB files.
Since STATIC libraries do not link their compiler PDB file becomes more
important. Add new target properties "COMPILE_PDB_NAME[_<CONFIG>]" and
"COMPILE_PDB_OUTPUT_DIRECTORY[_<CONFIG>]" to specify the compiler PDB
file location and pass the value to the MSVC /Fd option.
People will be tempted to put things there for convenience, thereby
causing conflicts similar to
http://thread.gmane.org/gmane.comp.compilers.clang.devel/35162/focus=35169
where it is conceivable that the LLVM developers could put a flag on
a target for convenience, which would cause conflicts for some downstreams.

behavior for existing projects that set the version variables themselves
prior to calling project(). Add policy CMP0048 for compatibility.

De-duplicate content in the QNX platform file by including the GNU

compiler id is in use, and the language is CXX. Use the QNX
recommended flag for QCC instead of the gcc compatible -x flag.
Populate new module files to handle system includes and depfiles
when using the QCC compiler.
Remove code which unsets the system include and depfiles related
variables. When a GNU driver is used instead of the QCC one, the
appropriate flags will be used. These variables were previously
cleared for lowest-common-denominator compatibility with both
drivers.

Extend the RunCMake.Configure test to verify that the build system
re-runs CMake when this input changes.
Add documentation entries for variables
CMAKE_OSX_ARCHITECTURES
CMAKE_OSX_DEPLOYMENT_TARGET
CMAKE_OSX_SYSROOT
Explain what each does and when/how they should be set.

Remove references to the UseQt4 file, which is obsolete in light of
the IMPORTED targets.
Add documentation for automatic tool invocation and options.
Remove reference to variables which should not be needed in modern
implementations.
