This property allow to specify a specific Visual Studio tool for a
source file overriding the default tool behavior. For example, a
`.resw` file being processed as a `PriResource` file. This has the
advantage of being able to teach CMake to process new file types without
code modifications.
Download http://www.gnu.org/licenses/lgpl.txt and place it as
Licenses/LGPLv3.txt in our source tree. When building cmake-gui, use
option CMake_GUI_DISTRIBUTE_WITH_Qt_LGPL to enable notification in the
"About" dialog of how the distribution of Qt is licensed. Install the
license file as ${CMAKE_ROOT}/Licenses/LGPLv3.txt so that the dialog can
display a path to it.
Factor the flag generation out of cmCommonTargetGenerator::GetFlags
into a new cmLocalGenerator::GetTargetCompileFlags method.
This will allow it to be used without a target generator available.
Add a cmLocalGenerator::GetTargetFortranFlags virtual method to get
generator-specific generation of Fortran-specific flags. Implement it
in cmLocalCommonGenerator by moving the implementation from
cmCommonTargetGenerator::AddFortranFlags. This will allow it to be used
without having a target generator available.

Move code to create/get the fortran module directory from the
cmCommonTargetGenerator to cmGeneratorTarget.
Rename the ComputeFortranModuleDirectory method to
CreateFortranModuleDirectory as this method *creates* the directory if
it is missing.
Even in relatively small projects using `--trace` (and `--trace-expand`)
may produce a lot of output. When developing a custom module usually
one is interested in output of only a few particular modules.
Add a `--trace-source=<file>` option to enable tracing only a subset of
source files. The final output would be only from requested modules,
ignoring anything else not matched to given filename(s).
Create a LINK_WHAT_YOU_USE target property and corresponding
CMAKE_LINK_WHAT_YOU_USE variable to enable this behavior.
Extend link commands by running `ldd -u -r` to detect shared
libraries that are linked but not needed.
In commit v3.6.0-rc1~279^2~10 (VS: in Clang/C2 toolset, setup correct
compiler settings, 2016-02-18) a flag mapping was added for the clang
`-Os` flag. However, this collides with a mapping we already had for
the MSVC flag of the same name. This is a symptom of a larger problem
in that the VS generators need a per-toolset flag map (issue #16153).
For now, simply drop the new mapping and drop `-Os` from clang compiler
flags in the MinSizeRel configuration.

Since 2.6.3 the UTILITY target may have source files. A defect was filed
that these files are now visible in the source tree. A fix later removed
all generated files from the source tree, regardless of the target type.
You can't even include them by using the SOURCES option. This fix adds
generated files again, except for the UTILITY target which cluttered the
source tree.
Fixes#14272.

The force parameter is ugly and makes the method harder to reason about
(issues the message ... but maybe it doesn't ... but then again you can
force it). It is a violation of
https://en.wikipedia.org/wiki/Interface_segregation_principle
and is the kind of thing described in a recent blog here:
http://code.joejag.com/2016/anti-if-the-missing-patterns.html
"Any time you see this you actually have two methods bundled into one.
That boolean represents an opportunity to name a concept in your code."
The makefile is only used when called by the cmMessageCommand, so inline
the use of it there. It otherwise creates an undesirable dependency on
cmMakefile for issuing messages in the cmake instance, a violation of
the Interface Segregation Principle.
https://en.wikipedia.org/wiki/Interface_segregation_principle
This also makes it more explicit that the variable definitions only
affect the message() command. If an AUTHOR_WARNING is issued for any
other reason, it is not affected. To affect that, it is necessary to
set the cache variable instead of the regular variable.
This is an unfortunate interface quirk, but one which can't be fixed
easily now.
Add a ``FIND_LIBRARY_USE_LIB32_PATHS`` global property analogous to the
``FIND_LIBRARY_USE_LIB64_PATHS`` property. This helps find commands on
multilib systems that use ``lib32`` directories and either do not have
``lib`` symlinks or point ``lib`` to ``lib64``.
When we are on OSX and we are launching cmake-gui from a symlink, the
application will fail to launch as it can't find the qt.conf file which
tells it what the name of the plugin folder is. We need to add this path
BEFORE the application is constructed as that is what triggers the
searching for the platform plugins
CMakeFindBinUtils sets CMAKE_RANLIB to `:` if it is not available in
order to get a no-op. This does not work on a Windows host build
environment that runs commands in `cmd` instead of `sh`. Teach the
Ninja and Makefile generators to simply skip the command if it is `:`.
This this was already done by the Makefile generator since commit
v2.6.0~3161 (BUG: Do not write link script lines that use the ':',
2006-06-18), but only when using a link script.

50a3d340 PackageMaker: factor out common code for creating pkg files.
Policy CMP0026 deprecated the LOCATION property, and we have long
provided a $<TARGET_FILE:...> generator expression. However, if
a project tries to use $<TARGET_PROPERTY:...,LOCATION> we should
at least not crash.
The compatibility implementation of the LOCATION property uses
cmGlobalGenerator::CreateGenerationObjects to create the structures
needed to evaluate the property before generation starts. The
implementation assumed that accessing the property could only be done
during configuration (via the typical get_property command use case).
The $<TARGET_PROPERTY:...,LOCATION> genex causes the LOCATION property
to be accessed during generation. Calling CreateGenerationObjects
during generation blows away all the objects currently being used for
generation and is not safe. Add a condition to call it only when
configuration is not finished.
Use clang-tidy's readability-simplify-boolean-expr checker.
After applying the fix-its, revise all changes *very* carefully.
Be aware of false positives and invalid changes.
Use clang-tidy's performance-unnecessary-copy-initialization checker.
After applying the fix-its (which turns the copies into const&), revise

Use clang-tidy's performance-unnecessary-value-param checker to find
value parameter declarations of expensive to copy types that are not

After applying the fix-its, manually change `const T&` to `T const&`.
d256ba07 try_compile: Optionally forward custom platform variables to test project
fb4791b3 cmCoreTryCompile: Refactor forwarding of variables to test project
Add a `CMAKE_TRY_COMPILE_PLATFORM_VARIABLES` variable to specify a list
of custom variables to be forwarded to a `try_compile` test project.
This will be useful for platform information modules or toolchain files
to forward some platform-specific set of variables from the host project
(perhaps set in its cache) to the test project so that it can build the
same way.
De-duplicate the logic that constructs the cmake `-D` flag used to pass
variables into the test project cache. Also subsume variables that were
propagated by generating `set()` commands in the project and pass them
as cache entries instead.

Manually extract the C++ portion of `cmListFileLexer.in.l` into a

Manually format C++ code inside the lexer actions to match our style.
Then re-generate the lexer.
Revise the documented modifications we need to make to the
flex-generated source file according to the needs of the new version.
Update our own implementation to avoid warnings with flex types.
Even though the `file(GLOB)` documentation specifically warns against
using it to collect a list of source files, projects often do it anyway.
Since it uses `readdir()`, the list of files will be unsorted.
This list is often passed directly to add_executable / add_library.
Linking binaries with an unsorted list will make it unreproducible,
which means that the produced binary will differ depending on the
unpredictable `readdir()` order.
To solve those reproducibility issues in a lot of programs (which don't
explicitly `list(SORT)` the list manually), sort the resulting list of
the `file(GLOB)` command.
A more detailed rationale about reproducible builds is available
[here](https://reproducible-builds.org/).
Add a `CMAKE_NINJA_OUTPUT_PATH_PREFIX` variable. When it is set, CMake
generates a `build.ninja` file suitable for embedding into another ninja
project potentially generated by an alien generator.
In WriteObjectBuildStatement we pass object file names and directories
to several places that expect paths as Ninja sees them. Convert them to
Ninja paths before all such uses.
All paths generated on Ninja-invoked command lines should be passed
through ConvertToNinjaPath. Fix ConvertToLinkReference to call this
instead of partially duplicating its implementation.
In `AppendTargetOutputs` we generate a logical build target name for
each UTILITY command. Simplify the logic to avoid testing the result
of `ConvertToNinjaPath`.

Packagers may now set their own rpm package
file names or request that rpmbuild tool
chooses one for them. It also supports handing
of situations where one spec file may produce
multiple rpm packages.
The empty string we add as a link item for an INTERFACE_LIBRARY target
is not a path, so do not mark it as such. The generators currently
tolerate it either way, but only by accident.
Set LC_NUMERIC = "C" at startup after Qt initializes the application
because Qt may have adopted the current locale from the environment.
CMake does not define behavior for non-C-locale numeric behavior.
Since commit v3.3.0-rc1~430^2 (Teach find_(library|file|path) to get
prefixes from PATH, 2015-02-18) we search in <prefix>/include and
<prefix>/lib directories for prefixes with bin directories in the PATH
environment variable. The motivation was to support MSYS, MinGW and
similar Windows platforms in their default environments automatically.
At the time this behavior was thought to be worthwhile in general.

afca3735 Help clang-format wrap after braces on long initializer lists
85425a3e Move comments off of class access specifier lines
64b55203 Isolate formatted streaming blocks with clang-format off/on
Teach the `add_custom_command` and `add_custom_target' commands to
substitute argv0 with the crosscompiling emulator if it is a target with
the `CROSSCOMPILING_EMULATOR` property set.
Add a long comment inside a few braced initializer lists in order to
convince clang-format to break after the opening brace and format the
list without indenting every value past the opening brace.
The clang-format tool may turn this:
public: // comment about access specifier
// unrelated comment indented with code
...
Into:
public: // comment about access specifier
// unrelated comment indented with code
...
Avoid this by moving comments off of access specifier lines.
The clang-format tool can do a good job formatting most code, but
well-organized streaming blocks are best left manually formatted.

Surround such blocks with the pair

in order to protect them from update by clang-format. Use the C-style
`/*...*/` comments instead of C++-style `//...` comments in order to

comments.
