This will allow additional information about the availability
and capabilities of extra generators to be queried without
actually creating them.
Instead of a static NewFactory() method like the main generator
factories have, use a static GetFactory() method to get a pointer to a
statically allocated extra generator factory. This simplifies memory
management.

Teach Visual Studio generators to include object files from object

The Makefile and Ninja generators already did this. Update the

They regress existing builds that depend on the paths/symbols generated
previously. Another approach will be needed to solve the name collision
problem they were intended to solve. Leave the error diagnostics for
the colliding cases that were added in the same topic as the above
commits because they provide a useful early failure in relevant cases.
Fixes#16209.
Factor CMAKE_<LANG>_USE_RESPONSE_FILE_FOR_{OBJECTS,LIBRARIES} lookup out
into a common helper. Use a separate helper for each because more
specific logic may be added to each later.
Custom command dependencies are followed for each target's source files
and add their transitive closure to the corresponding target. This
means that when a custom command in one target has a dependency on a
custom command in another target, both will appear in the dependent
target's sources. For the Makefile, VS IDE, and Xcode generators this
is not a problem because each target gets its own independent build
system that is evaluated in target dependency order. By the time the
dependent target is built the custom command that belongs to one of its
dependencies will already have been brought up to date.
For the Ninja generator we need to generate a monolithic build system
covering all targets so we can have only one copy of a custom command.
This means that we need to reconcile the target-level ordering
dependencies from its appearance in multiple targets to include only the
least-dependent common set. This is done by computing the set
intersection of the dependencies of all the targets containing a custom
command. However, we previously included only the direct dependencies
so any target-level dependency not directly added to all targets into
which a custom command propagates was discarded.
Fix this by computing the transitive closure of dependencies for each
target and then intersecting those sets. That will get the common set
of dependencies. Also add a test to cover a case in which the
incorrectly dropped target ordering dependencies would fail.
Although we provide a `VS_GLOBAL_ROOTNAMESPACE` option to both set
the `RootNamespace` value and reference it, some users may try to
set `VS_GLOBAL_RootNamespace` to set `RootNamespace` as a variant
of the `VS_GLOBAL_<variable>` property. In this case we still
need to add the reference to `$(RootNamespace)`.
Since commit v3.6.0-rc1~339^2 (CPack: Fix CPACK_INSTALL_CMAKE_PROJECTS
SubDirectory (4th) option, 2016-02-18) we now honor the "Directory"
option of this variable. Prior to that commit the value was not used
so projects may have used a placeholder value like `.` instead of `/`.
Treat `.` the same as `/` to restore compatibility with such projects.
Fixes#16205.
The cmGetPropertyCommand::StoreResult expects NULL for unset
properties. Make ALIASED_TARGET align with that expectation.
Additional corrections to the unit tests are necessary because
get_property removes variables for unset properties (in contrast
to get_target_property which stores a -NOTFOUND value).
Add an explicit `<Natvis>` element in VS project files for `*.natvis`
files. These enable custom debug visualizers for project-specific
types.
Fixes#16043.
Use `sysconf(_SC_ARG_MAX)` wherever `_SC_ARG_MAX` is available instead
of hard-coding an incomplete list of operating systems that implement
it. In particular, it is available on BSD platforms that were not
previously listed.
Commit v3.6.0-rc1~174^2~1 (cmGlobalNinjaGenerator: Clarify logic for
forcing use of response files, 2016-04-06) started using negative
command line length values to represent forced use of response files but
forgot to update `calculateCommandLineLengthLimit()` accordingly. Teach
it to return `0` instead of `-1` when no limit is computed from the
system to avoid forcing response files.

This code has accidentally not been compiled since commit
v3.0.0-rc1~556^2 (cmake: Split -E command implementation into separate
source file, 2013-10-03) because CMAKE_HAVE_VS_GENERATORS was local to
`cmake.cxx`.
Fixes#16195.
This code has not been compiled since commit v3.0.0-rc1~556^2 (cmake:
Split -E command implementation into separate source file, 2013-10-03).
It appears the code was never used since it was added anyway.
Files generated by `install(EXPORT)` and `export_library_dependencies()`
may be installed with packages and consumed by dependents. In order to
avoid re-building dependents only because the version of CMake changed,
drop the CMake version from the export file content.
The fix in commit commit v3.6.0-rc1~82^2 (Drop find_(library|file|path)
prefixes from PATH on non-Windows, 2016-05-09) aggressively dropped
search of the entries in PATH itself in addition to the prefixes derived
from it. This regresses find modules that (incorrectly) depended on the
behavior, including some of our own modules such as FindImageMagick.
Restore the search of entries in PATH itself. If we want to drop it
later we will need to do so with a policy. Fixes#16192.
Factor the implementation out of cmMakefileLibraryTargetGenerator
into a helper method in cmMakefileTargetGenerator so it can be
re-used elsewhere later.
Drop our `HaveExportedObjects` check before dumping exports for an
object file. It is possible for only a subset of needed symbols to have
explicit markup, and re-exporting the marked symbols does not hurt.
This leaves no callers of `HaveExportedObjects`, but leave the
method in place anyway because it may be useful in the future.
Fixes#16161.
Replace use of cmsys::auto_ptr with a CM_AUTO_PTR macro that maps to
our own implementation adopted from the KWSys auto_ptr implementation.
Later we may be able to map CM_AUTO_PTR to std::auto_ptr on compilers
that do not warn about it.
Automate the client site conversions:
git grep -l auto_ptr -- Source/ | grep -v Source/kwsys/ | xargs sed -i \
's|cmsys::auto_ptr|CM_AUTO_PTR|;s|cmsys/auto_ptr.hxx|cm_auto_ptr.hxx|'
In the `try_compile` source file signature we propagate the caller's
value of `CMAKE_<LANG>_FLAGS` into the test project. Extend this to
propagate `CMAKE_<LANG>_FLAGS_<CONFIG>` too instead of always using the
default value in the test project. This will be useful, for example, to
allow the MSVC runtime library to be changed (e.g. `-MDd` => `-MTd`).
However, some projects may currently depend on this not being done,
so we need to activate the behavior using a policy.
This change was originally made by commit v3.6.0-rc1~160^2 (try_compile:
Honor CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11) but without the
policy and so had to be reverted during the 3.6 release candidate cycle.
Fixes#16174.
Clang refuses to default initialize an instance of a class that does not
have a default constructor. Fix the check by adding default
constructors. Don't use brace initialization like it is proposed in the
error message. We want to test the override support independent from
the support for brace initialization.
Revert commit v3.6.0-rc1~160^2 (try_compile: Honor
CMAKE_<LANG>_FLAGS_<CONFIG> changes, 2016-04-11). The behavior it
introduced can break projects that depend on the lack of such behavior.
We will have to introduce a policy or other mechanism to enable the
behavior in a compatible way. Simply revert it for now.
See issue #16174.
