The most likely documentation page a project author will read in
response to a policy warning is the page for the policy itself.
Add to every policy documentation page a note explicitly stating
that the OLD behavior is deprecated. Also mention this in the
cmake_policy() command documentation that explains how to set a
policy to OLD.

Revert commit v3.3.0-rc1~435^2 (Windows-GNU: Do not tell find_library to
treat '.dll' as linkable, 2015-02-18). MinGW tools support linking to
'.dll' files directly and many non-CMake build systems still do not
provide a separate '.dll.a' file.
When documenting in the COMMAND option how to reference an executable,
we previously only explicitly covered how to do it for argv[0] and left
it to the reader to follow the reference to the generator expressions
manual. Add explicit mention of the TARGET_FILE genex in this
documentation since it will be a commonly used generator expression in
this context.
The test for this variable was removed in commit v2.8.8~330^2~7 (complex:
Remove ancient unused ComplexRelativePaths test, 2011-12-23).
Commit v3.1.0-rc1~425^2~2 (backtrace: Convert to local paths in
IssueMessage, 2014-03-12) appears to have accidentally made some backtraces
print relative paths with the variable because conversions which used to be
done at configure time, before the variable had an effect are now potentially
done at generate time.
The documentation of the variable says not to use it, and the docs are wrong in
that the variable actually applies in per-directory scope.
The read of the variable makes it harder to split conversion methods from
cmLocalGenerator where they don't belong. Remove it now.
Add section headers similar to the 3.2 release notes and move each
individual bullet into an appropriate section. Revise and consolidate

CMake-generated targets are not supported by add_dependencies. State
this explicitly and use 'install' as an example since this may be
commonly attempted.
target_link_libraries() is being used in the example code but
target_include_directories() was probably meant to be used. The sentence
that starts with "Consuming code then" indicates that the example is
about using the appropriate include directory.
The <LANG>_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN were first
merged in commit v2.8.12~322 (Merge topic 'VISIBILITY_PRESET-property',
2013-06-05) but worked only for shared libraries and executables with
exports. Prior to commit v3.0.0-rc1~581^2 (GenerateExportHeader:
Deprecate add_compiler_export_flags function., 2013-09-02) the
add_compiler_export_flags function was used to add visibility flags to
all targets.
The visibility flags are useful for sources in all target types because
they may be later linked into shared libraries or executables with
exports. Introduce policy CMP0063 to enable them for all target types
while preserving compatibility with existing projects that do not expect
this.
Add an ExternalData_NO_SYMLINKS to enable use of copies instead of
symlinks to populate the real data files behind a DATA{} reference.
This will be useful on UNIX-like systems when the underlying filesystem
does not actually support symbolic links.

This reverts commit f85db2f323.
Discussion by the QtCreator community at
https://bugreports.qt.io/browse/QTCREATORBUG-13695
raises concerns about this particular approach to working with CMake
projects using QtCreator. Also, the functionality and design of the QBS
extra generator was never discussed on the CMake mailing list or with
QtCreator developers. There may be better ways to make the two tools
work together.
In order to avoid committing to long-term support of this generator
prior to such discussion taking place, revert it from CMake for now.
We may restore this or use an alternative design based on results of
such discussion.

Create a <LANG>_INCLUDE_WHAT_YOU_USE target property (initialized by a

The find_package command, on Windows, has always searched build trees
recently visited by cmake-gui (or CMakeSetup at one time). This was
done when the command was created with the intention of simplifying
workflows involving building multiple dependent projects. However,
this behavior depends on recent developer interaction and therefore
can create different find results based on transient system states.
It can lead to surprising results and user confusion.
Since this behavior was first added CMake has gained many more search
options, better error messages when a package is not found, and a
package registry. The latter in particular allows projects to make
their build trees available for dependent projects to find without
user intervention. Therefore the originally intended workflow can
be achieved in other, more stable ways.
After the above evoluion of find_package we have now decided that
the magic search-where-cmake-gui-was behavior does more harm than
good. Drop it. We do not need a policy for this behavior change
because it only affects interactive use.
Use the KWSys Process "MergeOutput" option to give the child process
the same pipe (or file) for both stdout and stderr. This allows
natural merging of stdout and stderr together instead of merging
on arbitrary buffered read boundaries as before.
5731fb2e ctest_build: mention CTEST_BUILD_COMMAND in the docs

MAIN_DEPENDENCY limitation, 2015-03-09) and the follow up commit
b372a99a (UseSWIG: Do not use MAIN_DEPENDENCY on custom commands,
2015-03-26).
I misdiagnosed the underlying issue that prompted creation of policy CMP0057.
The actual issue surfaces when a single custom command's MAIN_DEPENDENCY
is listed in more than one target; this issue will have to be addressed
independently.
The previous example for CMP0054 did not show how critical the policy is
since the result is the same in both cases (NEW and OLD behavior).
Instead show an example when the policy does make a difference.
Add sections to the cmake-buildsystem(7) manual and cross-reference
them with relevant variables and target properties. This avoids
duplicating the information and allows it to be more detailed.
Many projects put their project() call first, but the actions taken
by this command can be influenced by policies and other information
set by a call to cmake_minimum_required. Document in each of these
two commands that cmake_minimum_required should be called first.

The documentation of this variable in the CTest module is outdated
and has been superseded by the ctest(1) manual. In particular, the
latter mentions that it works with the Ninja generator as well as
makefile generators. Remove the documentation from the CTest module

already references the ctest(1) manual).

Green Hills MULTI is an IDE for embedded real-time systems. The IDE's
product page can be found here:
http://www.ghs.com/products/MULTI_IDE.html
It supports cross compiling on ARM, Intel x86, and other architectures
with various operating systems. The IDE exists on Linux and Windows
host systems, but CMake will currently only generate the project files
on Windows host systems.
The UPPERCASE name was inconsistent with config-packages, the
find_dependency macro, and even FPHSA itself, which expects
components to be specified with names matching ExactCase.
The FOUND_VAR was only permitted to have two possible values, and
now both are set for compatibility. Document it as obsolete, and
adjust the code for the same. Users of the variable should just
remove it.

882f48e5 Link libraries by full path even in implicit directories
318cd370 Help: Add link target for Find Modules section of cmake-developer.7
1535dcd8 Tests: Teach RunCMake to optionally merge command output to stdout
When CMP0003 was first introduced we wanted to link all libraries by
full path. However, some projects had problems on platforms where
find_library would find /usr/lib/libfoo.so when the project really
wanted to link to /usr/lib/<arch>/libfoo.so and had been working by
accident because pre-CMP0003 behavior used -lfoo to link.
We first tried to address that in commit v2.6.0~440 (Teach find_library
to avoid returning library paths in system directories, 2008-01-23) by
returning just "foo" for libraries in implicit link directories. This
caused problems for projects expecting find_library to always return a
full path. We ended up using the solution in commit v2.6.0~366 (...
switch library paths found in implicit link directories to use -l,
2008-01-31). However, the special case for libraries in implicit link
directories has also proven problematic and confusing.
Introduce policy CMP0060 to switch to linking all libraries by full path
even if they are in implicit link directories. Explain in the policy
documentation the factors that led to the original approach and now to
this approach.
Prefix test commands with the CROSSCOMPILING_EMULATOR property

If the CMAKE_CROSSCOMPILING_EMULATOR variable is defined, and

the try_run executables. This prevents the need to populate
TryRunResults.cmake when cross compiling.

Many places in our documentation refer to "Makefile Generators" or
"Visual Studio" generators as a group of generators. Give such
places a linkable document section to reference since they cannot
cross-reference the individual generators in the groups.
Explain at the beginning of the section the requirements for a package
to be relocatable to justify the rest of the section content.
Generalize example to use fictional package names instead of real ones,
especially because FindBoost provides no alternative yet. Reword the
discussion to represent the preferred approach as "ideal" but also
suggest workarounds when find modules do not provide the imported
targets.
Re-organize the content added to the cmake-packages(7) manual by
* commit v3.0.0-rc1~184^2 (Help: Document export(EXPORT) in the
cmake-packages manual, 2013-12-23),
* commit v3.0.0-rc1~154^2~1 (Help: Add notes about relocatability
of config-file packages, 2014-01-07), and
* commit v3.2.0-rc1~345^2 (Help: Warn that paths should not be used
in INTERFACE_ build properties, 2014-11-22).
These commits broke the natural flow of the original manual and made
wording after the new content make less sense. Move the content into
new subsections to restore the flow of the original manual and to
make explicitly the purpose of the new content.
Shorten the relocatable usage requirement "warnings". Refer to the
new cmake-packages(7) manual subsection to reduce duplication. Also
clarify the distinction between paths to library dependencies and
paths to their header files.
These notes apply only for the use case of creating a package for
redistribution on machines other than that where it is built. Clarify
this to readers by placing the discussion in dedicated sections titled
accordingly.
Beginning in CUDA 5.5 a static version of the cuda runtime library
became available. Since nvcc defaults to using this library over the
shared version, FindCUDA will also default to using this version. There
are many advantages to using the static version (most importantly to
avoid conflicts with multiple versions when building a CUDA based
library). Offer a CUDA_USE_STATIC_CUDA_RUNTIME option to control
this behavior.
Add policy CMP0059 to cover this change. The property has been
deprecated since CMake 2.4 anyway.
This will help clean up cmMakefile -- the DefineFlagsOrig member should
not need to exist.
Much of the information in the old set() command documentation is now
covered in the cmake-language(7) manual. Rewrite the documentation
with this in mind. Split up the signatures for each kind of variable
into different subsections.
Make wording of the directory and target properties more consitent
and complementary. Specify that the value is a ";-list" with a link
to the cmake-language(7) manual section on lists.
Revert commit v3.0.0-rc1~175^2~20 (add_dependencies: Disallow use with

Add policy CMP0058 to avoid generating 'phony' ninja rules for unknown
custom command dependencies. This requires projects to specify their
custom command byproducts explicitly. With this requirement we no
longer have to assume that unknown custom command dependencies are
generated and can instead simply assume they are source files expected
to exist when the build starts. This is particularly important in
in-source builds. It is also helpful for out-of-source builds to allow
Ninja to diagnose missing files before running custom command rules that
depend on them.

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.

The find_package command already knows how to compute installation
prefixes from PATH. Use the same approach to establish prefixes for
find_library, find_file, and find_path to use to look in directories
like "<prefix>/lib[/<arch>]" and "<prefix>/include" for libraries and
headers. This will reduce the amount of configuration end users need to
do to establish a work environment rooted under a specific prefix.

This will allow us to use a value other than just the config name
for the project OutputDirectory setting used for $(OutDir).
Also use $(ConfigurationName) instead of $(OutDir) for the link
directory configuration suffix since that is a hard-coded instance of
a use case for CMAKE_CFG_INTDIR.
This will allow per-config destinations for targets in EXPORT sets.
Using multiple install(TARGETS) with separate CONFIGURATIONS is
rejected as a target appearing more than once in an export set.
Now instead one can write
install(TARGETS foo EXPORT exp DESTINATION lib/$<CONFIG>)
to get a single logical membership of the target in the export set
while still having a per-config destination.

In commit v3.0.0-rc1~9 (Help: Rename 3.0 release notes to 3.0.0,
2014-02-19) we anticipated the possibility of bugfix-only release notes.
However, in practice we have no release notes for bug fix releases
because we do not cover bug fixes in release notes at all, only new
features. Instead we've been updating the feature-level release notes
document in bug fix releases, treating errors in the document as bugs.
It makes more sense to maintain release notes at the feature-release
level, so rename the documents accordingly. Also update the document
titles and intro text to refer only to feature versions and not bugfix
versions.
