Expand the -W set of cmake options to include support for the -Werror
and -Wno-error format, which is used to control upgrading and
downgrading warning and error messages. Implement support for these new
formats for the dev and deprecated message types.
Add tests and updated documentation for new options.
Remove the duplicate code in cmake::Configure to set the cache variables
for the warning message suppression. Replace it with calls to the
dedicated methods to carry this out.
Create a new dialog window for the cmake-gui that provides controls for
setting the state of suppression of developer and deprecated warning
messages. This replaces the previous single checkbox for setting the
state of suppression of developer warnings.
Added a note for the new functionality to the release notes.
Explicitly enable deprecated warnings by default, via the
cmake::GetSuppressDeprecatedWarnings method, which signals
suppression is turned off unless the CMake variables are set
as required.
Add tests and update the documentation for the new
functionality.
Add 'deprecated' warning options type, to allow setting
CMAKE_WARN_DEPRECATED via the -W '-Wdeprecated' and
'-Wno-deprecated' options.
Add tests for new options and updated documentation.
Refactor the -Wdev and -Wno-dev options parser to use a generic -W
parser that follows the GCC pattern, excluding support for
-Werror=TYPE and -Wno-error=TYPE formats for now.
Explicitly enable author warnings by default, via the
cmake::GetSuppressDevWarnings method, which signals suppression
is turned off unless the CMake variables are set as required.
Add test cases for author and deprecated messages displayed by
default.
Make the message suppression more consistent, by adding a check
for the message related CMake variables in cmake::IssueMessage,
which allows callers of IssueMessage other than the message
command to behave as expected. Also added a check for
CMAKE_SUPPRESS_DEVELOPER_WARNINGS in the message command to
mirror the deprecated message type behaviour.
Added a 'force' flag to the cmake::IssueMessage method, to
make the message suppression consistent, when setting the
message related CMake variables directly in a CMake file.
Expand message command tests to cover the AUTHOR_WARNING message
type as well.
The -T parameter to CMake may now be specified through cmake-gui via a
new text field in the first-time configure wizard (below the generator
chooser).
The generator factories specify whether or not they support toolsets.
This information is propagated to the Qt code and used to determine if
the selected generator should also display the optional Toolset widgets.
The changes in commit c96fe0b4 (cmake: Add -W options to control
deprecation warnings and errors, 2015-07-28) fail to account for
-Wdev warnings produced by places in CMake other than message().
This causes a regression in which -Wno-dev fails to suppress such
warnings. Revert the feature until it can be revised accordingly.
heaptrack showed a 1 byte allocation with the backtrace pointing
here, as is the case since commit v3.3.0-rc1~112^2~5 (cmPolicies:
Remove unused cmPolicy class., 2015-05-03)
Refactor the -Wdev and -Wno-dev to use a generic -W parser that follows
the GCC pattern. Include support for setting CMAKE_ERROR_DEPRECATED and
CMAKE_WARN_DEPRECATED via the deprecated warning. Add -Werror=dev and
-Wno-error=dev options so that dev warning options are in line with
deprecated warning options. Use a new CMAKE_SUPPRESS_DEVELOPER_ERRORS
internal cache entry to store the above new dev options persistently.
Add tests for new options and updated cmake documentation and release
notes to list new options.
The --trace option is helpful, but sometimes, what you're looking for is
deep under many layers of function calls and figuring out what instance
of the function call you're looking at is tedious to determine (usually
involving patching and message()). Instead, add a --trace-expand option
to trace while expanding commands into what CMake actually sees.
Don't create a snapshot in Initialize(), but leave the creation
responsibility to the cmake instance instead. Previously, the
cmState would Initialize() in its constructor, and the cmake instance
would re-Initialize() during Configure(). The end result was the
same and there would be one snapshot present. However, cmLocalGenerator
also created a snapshot on construction, and that one was used, leaving
the first snapshot unused, and potential for off-by-one errors.
Fix that by making the cmLocalGenerator use the existing snapshot
if it is top-level. Add a CurrentSnapshot to the cmake instance and
populated it while configuring a directory. This will eventually
replace the 'current local generator' concept. Fix the GetParent
implementation to be able to return the first snapshot.
Always show the option with its argument separate in summary text.
State in the main documentation that the option and its argument can be
given together too.
They are maintained as containing the same content as the 'home'
directories, but they are never read from.
Fix some comments and help strings which confused the two by
name. They actually mean what is called CMAKE_SOURCE_DIR in
cmake code.
Global properties are already global in scope, so remove the
overload for specifying it and port users of the API.
The call from cmMakefile::GetProperty can be simplified because
the scope is only used during chaining, and there is no further
chaining after processing global properties.
At this point, it is an interface to the cache. It will be extended
to be a universal interface for access to and manipulation of
configuration-time data (defintions, properties on targets,
directories, source files etc).
This will allow porting all command implementations away
from the cmMakefile and cmTarget classes, and result in something
more-purely related to configuration-time processing of cmake
commands. That should serve at least the following goals:
* Split the CMake implementation more definitively into three
stages: Configuration, computation and generation, and be able to
implement each optimally for memory access patterns etc.
* Make better IDE integration possible by making more configuration
data available.
* Make it possiblte to use a smaller library than CMakeLib.a in
cpack and ctest, resulting in smaller executables.
* Make it possible to run the configure step multiple times in
the same CMake run (#14539).
Manage its lifetime in the cmake class, and add a convenience accessor
to cmMakefile.

This topic was never tested without some follow-up commits. The
GetCacheEntryValue API returns a pointer to memory freed on return.
It will have to be revised along with the rest of the original topic.
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.
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.
