When exporting from a project (with install(EXPORT ...)), the
`<PROJECT>Targets.cmake` file contains logic for computing the
`_IMPORT_PREFIX` from its own location. This `_IMPORT_PREFIX` is then
used in the `<PROJECT>Targets-<config>.cmake` file to generate the
`IMPORTED_LOCATION_<CONFIG>`. The generation unconditionally appends a
"/" to `_IMPORT_PREFIX` before appending the rest of the path. If
`_IMPORT_PREFIX` is "/", then the `IMPORTED_LOCATION_<CONFIG>`
properties all start with exactly two leading slashes ("//").
Exactly two leading slashes is a special case in POSIX file paths, such
that its interpretation is left up to the implementation. This means
that changing the path prefix from "/" to "//" should not be allowed.
Since references to `_IMPORT_PREFIX` are always followed by a "/",
simply check the value to replace "/" with "".
Since commit 14a8d61f (cmMakefile: Port nested error logic away from
cmExecutionStatus) we fail to continue processing function and macro
bodies after non-fatal errors. A non-fatal error should not stop
foreach loops, macro bodies, nested bodies, or the outer script.
Add a test covering these cases, and revert the change to fix them.
Also revert commit 2af853de (cmMakefile: Simplify IssueMessage
implementation) because the assertion it added (which was removed by the
above commit and is restored by reverting it) is incorrect. We do have
code paths that call cmMakefile::IssueMessage with an empty execution
stack, such as in CheckForUnusedVariables's LogUnused call.
Our parser grammar expects all statements to end in an `EOSTMT` token
such as a newline. Ensure that the last statement in a file can be
parsed even if it is missing a newline.
Revise the documented modifications we need to make to the
flex-generated source file according to the needs of the new version.
Also drop the duplicate copyright notice block from the generated file.
We expect to handle all relevant statements and ignore those that we do
not understand. Warn if this process ever fails. Otherwise dependency
information may be silently left out.

The definitions have been introduced to ensure that cout and cerr are
not used in certain files. However, this limitation does not apply to
all source files that require cmCTest.h to be included. Furthermore,
the definitions cause side effects depending on the include order. In
total, the definitions do more harm than good. Remove them.
Since commit v3.5.0-rc1~58^2 (install: Allow generator expressions in
DIRECTORY, 2016-01-12) we accidentally treat leading generator
expressions as relative paths even though they may evaluate to absolute
paths. Defer the conversion to an absolute path until after evaluation.

When using the Clang Code Model in QtCreator, it turned out that having
the C system include dirs can make it report false positives for most
uses of the STL. This is due to the order the Clang Code Model looks at
the include directories and some C includes in /usr/include could be
incompatible with the used STL if found first.

The Intel 16 format starts with the 0x0A 0x00 sequence that we use to
skip past the timestamp. This occurrence appears to be a version

Ideally we should gain a better understanding of the format and avoid
depending on short sequences that are likely to appear early by
coincidence, but this approach will suffice for now.

With the Makefile generator one can use `cd $subdir; make install` to build and
install targets associated with a given subdirectory. This is not possible to
do with the Ninja generator since there is only one `build.ninja` file at the
top of the build tree. However, we can approximate it by allowing one to run
`ninja $subdir/install` at the top of the tree to build the targets in the
corresponding subdirectory and install them.
This also makes sense for `test`, `package`, and other GLOBAL_TARGET targets.
It was already done for `all` by commit v3.6.0-rc1~240^2~2 (Ninja: Add
`$subdir/all` targets, 2016-03-11).
In cmGlobalNinjaGenerator::AppendTargetOutputs we previously
handled GLOBAL_TARGET outputs specially in order to avoid adding
directory components to the output. However, this is not necessary
because cmNinjaTargetGenerator::New already filters out copies of
these targets that are not at the top level. Instead we can simply
follow the same output computation code path as UTILITY targets.
CMake used to put all header search paths into HEADER_SEARCH_PATHS
attribute. Unfortunately this attribute does not support to declare
a search path as a system include.
As a hack one could add a -isystem /path to the cflags but then include
ordering is not deterministic. A better approach was chosen with this
patch by not filling HEADER_SEARCH_PATHS at all and to populate
the C, C++, and Fortran flags directly. The include paths used by
Xcode should be now identical to the ones used by Unix Makefiles and
Ninja generator.
The implementation of `install(EXPORT)` generates files into a staging
directory for later installation. We use the full install destination
in the path to the staging directory to avoid collisions. In order to
avoid exceeding maximum path lengths (especially on Windows) we compute
a hash of the install destination when it is too long. Fix this logic
to account for the length of the file name(s) when deciding whether to
switch to the hashed name.

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.

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 not been compiled since commit v3.0.0-rc1~556^2 (cmake:

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.

This is important for two reasons:
1. A compiler might warn about a class that has a virtual member
function but no virtual destructor. We don't want to treat the feature
as incomplete in this case.
2. MSVC10 supports the override identifier except on destructors. In
this case, the feature really is incomplete and we want to detect it as
such.
In commit v3.6.0-rc1~174^2 (Ninja: Honor CMAKE_NINJA_FORCE_RESPONSE_FILE
for compile rules, 2016-04-06), Ninja learned to look for
`CMAKE_NINJA_FORCE_RESPONSE_FILE` in the current scope or the
environment in order to force response file usage for all compilation
rules.
However, on Windows, the RC compiler goes through cmcldeps which does a
`replace(output, output + ".dep.obj")` on the command line. However,
with a response file (which we name `output + ".rsp"`), the response
file path is replaced instead causing the compiler to (correctly)
complain that the response file `output + ".dep.obj.rsp"` does not
exist.
What needs to happen is for cmcldeps to look through the response file,
replace *its* contents and place it in the `output + ".dep.obj.rsp"`
file.
Also add a test which actually compiles an RC file into a library and
executable for all generators on Windows and additionally test
`CMAKE_NINJA_FORCE_RESPONSE_FILE` for Ninja generators.
