Allow the `Swift` language to be enabled with the Xcode generator for
Xcode >= 6.1. Reject it on other generators and with older Xcode
versions. Since Apple is the only vendor implementing the language
right now, the compiler id can be just `Apple`.
Added new USES_TERMINAL option to the ExternalProject_Add_Step
function. This option passes USES_TERMINAL to the underlying
add_custom_command call so that the Ninja console pool is used.
Also, corresponding new USES_TERMINAL_<step> options were added
to the ExternalProject_Add function.
Justification: if using Ninja with a CMake superbuild, it's often
desirable to limit the superbuild to ONE sub-Ninja process at a
time to avoid oversubscribing the CPU. Using the console pool also
makes it easy to monitor the progress of the sub-Ninja process.
Independent USES_TERMINAL_<step> arguments are passed to
ExternalProject_Add instead of one USES_TERMINAL argument that
controls everything. Users may wish to run some steps in parallel
but not others (e.g. parallelize configure but not build).
Create target property WINDOWS_EXPORT_ALL_SYMBOLS to automatically
generate a module definition file from MS-compatible .obj files and give
it to the linker in order to export all symbols from the .dll part of a
SHARED library.
Add a TestLoad setting to CTest that can be set via a new --test-load
command-line option, CTEST_TEST_LOAD variable, or TEST_LOAD option to
the ctest_test command. Teach cmCTestMultiProcessHandler to measure
the CPU load and avoid starting tests that may take more than the
spare load currently available. The expression
<current_load> + <test_processors> <= <max-load>
must be true to start a new test.

The Concurrent Fortran compiler (ccur.com) is available on Linux and can
be used much like the GNU Fortran compiler. Currently it has no
preprocessor symbols to identify it so we need to detect it by matching
compiler output.

Create a <LANG>_COMPILER_LAUNCHER target property (initialized by a
CMAKE_<LANG>_COMPILER_LAUNCHER variable) to specify a compiler launcher
tool. This will supersede the CMAKE_<LANG>_COMPILER_ARG1 approach to
using such tools. The old approach set CMAKE_<LANG>_COMPILER to the
launcher tool while the new approach leaves this variable set to the
actual compiler.
Implement this property for Makefile and Ninja generators. It cannot be
implemented for VS or Xcode generators as the IDE build tools offer no
such hooks.
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
some bullets covering related areas.
Move all development release notes into a new version-specific document:
tail -q -n +3 Help/release/dev/* > Help/release/3.3.rst
git rm -- Help/release/dev/*
except the sample topic:
git checkout HEAD -- Help/release/dev/0-sample-topic.rst
Reference the new document from the release notes index document.
Add a title and intro sentence to the new document by hand.
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
CMAKE_<LANG>_INCLUDE_WHAT_YOU_USE variable) to specify an IWYU command
line to be run along with the compiler.
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.
We never implemented them for VS 11 (2012), 12 (2013), or 14 (2015).
For VS 10 (2010) the reload macro does not work correctly when run from
inside a build launched through the IDE because stopping the build kills
the CMake that is driving the reload. Fortunately VS >= 10 know how to
reload the whole solution anyway.

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
for target executables. This allows test suites to be run on the host
when crosscompiling.
If the CMAKE_CROSSCOMPILING_EMULATOR variable is defined, and
CMAKE_CROSSCOMPILING is TRUE, then use CMAKE_CROSSCOMPILING_EMULATOR to run
the try_run executables. This prevents the need to populate
TryRunResults.cmake when cross compiling.
Extend sentences in other documentation linking to this manual to
say that it has a list of supported compilers.

ba9b9d79 Help: Fix syntax in non-relocatable usage requirements example
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.
