Since commit 9a6ff950 (Fix for bug where VS2010 did not use .obj files as
part of the build, 2011-04-01) and commit b291d9e7 (VS10: Fix external
objects generated outside target, 2012-03-19) we try to detect whether an
external object file is also a custom command output in the same target.
This is because VS10 includes .obj custom command outputs on the link line
by default.
VS 11 supports a "<LinkObjects ...>false</LinkObjects>" setting in custom
command rules to tell VS not to link the outputs. From the VS help:
Specify whether the Inputs and output files with specific extensions (.obj,
.lib, .res, .rsc) are passed to the linker.
Treat all external object files the same and add "<Object>" settings for them.
The member variable is checked to determine whether to call
HandleMissingTarget(). As that could be called during the loop in
the comming commits, ensure that it contains all targets being
exported.
Constructs such as these are an error as they are direct self-references:
set_property(TARGET foo APPEND PROPERTY
INCLUDE_DIRECTORIES $<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>)
set_property(TARGET foo APPEND PROPERTY
INCLUDE_DIRECTORIES $<TARGET_PROPERTY:INCLUDE_DIRECTORIES>)
However, this is an indirect self-reference in a cycle, and not an error:
set_property(TARGET foo APPEND PROPERTY
INCLUDE_DIRECTORIES $<TARGET_PROPERTY:bar,INCLUDE_DIRECTORIES>)
set_property(TARGET bar APPEND PROPERTY
INCLUDE_DIRECTORIES $<TARGET_PROPERTY:foo,INCLUDE_DIRECTORIES>)
The TARGET_NAME expression, which requires a literal, provides
target names. $<TARGET_PROPERTY:tgt,prop> also provides target
names in the cases where tgt is a literal, so that TARGET_NAME is
not needed then in addition.
This is for specifying INCLUDE_DIRECTORIES relevant to the build-location
or the install location for example:
set_property(TARGET foo PROPERTY
INTERFACE_INCLUDE_DIRECTORIES
"$<BUILD_INTERFACE:${CMAKE_CURRENT_BINARY_DIR};${CMAKE_CURRENT_SOURCE_DIR}>"
"$<INSTALL_INTERFACE:${CMAKE_INSTALL_PREFIX}/include>"
)
A 'bar' target can then use:
set_property(TARGET bar PROPERTY
INCLUDE_DIRECTORIES
"$<TARGET_PROPERTY:foo,INTERFACE_INCLUDE_DIRECTORIES>"
)
and it will work whether foo is in the same project, or an imported target
from an installation location, or an imported target from a build location
generated by the export() command.
Because the generator expressions are only evaluated at build-time, these
new expressions are equivalent to the ZeroNode and OneNode.
The GeneratorExpression test is split into parts. Some shells can't run
the custom command as it is getting too long.

Previously we hard-coded a list of implicit framework directories but
did not account for CMAKE_OSX_SYSROOT or for changes to the list across
OS X versions. Instead we should automatically detect the framework
directories for the active toolchain.
The parent commit added the "-Wl,-v" option to ask "ld" to print its
implicit directories. It displays a block such as:
Framework search paths:
/...
Parse this block to extract the list of framework directories.
Detection may fail on toolchains that do not list their framework
directories, such as older OS X linkers. Always treat the paths
<sdk>/Library/Frameworks
<sdk>/System/Library/Frameworks
<sdk>/Network/Library/Frameworks # Older OS X only
/System/Library/Frameworks
as implicit. Note that /System/Library/Frameworks should always be
considered implicit so that frameworks CMake finds there will not
override the SDK copies.
Refactoring in commit 8d674e78 (Ninja: move -LIBPATH behind -link
option, 2012-09-26) accidentally added code that overwrites the
framework search path flags on each iteration instead of appending.
Change '=' to '+=' to fix it. This affects Makefile and Ninja
generators.
Extend documentation for CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES to
explain how it is used by CMake and how it can be influenced by
environment variables.

f0d9385 Makefile: Use modern link information for framework search paths
2bc22bd Xcode: Add frameworks search paths from link dependeny closure (#13397)
Use cmComputeLinkInformation::GetFrameworkPaths to get the list of
framework paths needed by the linker. Drop the now unused framework
information from the old-style cmTarget link dependency analysis.
This should finally fix#13667 and #13762.
Instead of adding special handling to guess whether implicit include dirs
may have been removed, simply make it possible to query the include dirs
without removing the implicit ones.
Alex
The Xcode generator produces FRAMEWORK_SEARCH_PATHS from:
(1) Include directories of the form /path/to/Foo.framework become
-F/path/to so '#include <Foo/H>' can find H in the framework.
(2) Linked frameworks of the form /path/to/Foo.framework become
-F/path/to -framework Foo so the linker can find the framework.
Originally commit 82bb6fae (add framework support to FIND_FILE,
2005-12-27) added these and used the (then current) old-style link
dependency analysis results to get the frameworks. Later a second
setting was added by commit 2ed6191f (add initial xcode framework stuff,
2007-05-08) to transform -F/path/to linker options produced by the old
link line generation into entries appended to FRAMEWORK_SEARCH_PATHS.
Then commit 96fd5909 (Implement linking with paths to library files,
2008-01-22) updated the second setting to directly use the results of
full modern link dependency analysis, but forgot to remove the use of
old-style link results from the original setting location.
The two settings worked together for a while, with the second one
appending to the first. Then commit f33a27ab (Generate native Xcode 3.0
and 3.1 projects, 2009-06-29) changed the internal representation format
produced by the first setting but did not update the second setting to
append to the new representation. As a result, if the first setting
added any paths (usually via the old-style link analysis) then the
second setting containing the modern link analysis results would not be
applied at all.
Fix this by removing use of the old-style link analysis results.
Replace it using the modern link dependencies and remove the second
setting altogether. Now all values for FRAMEWORK_SEARCH_PATHS are
collected in one place so no special append logic is needed.
Historically CMake has always expanded ${} variable references in the
values given to include_directories(), link_directories(), and
link_libraries(). This has been unnecessary since general ${}
evaluation syntax was added to the language a LONG time ago, but has
remained for compatibility with VERY early CMake versions.
For a long time the re-expansion was a lightweight operation because it
was only processed once at the directory level and the fast-path of
cmMakefile::ExpandVariablesInString was usually taken because values did
not have any '$' in them. Then commit d899eb71 (Call
ExpandVariablesInString for each target's INCLUDE_DIRECTORIES,
2012-02-22) made the operation a bit heavier because the expansion is
now needed on a per-target basis. In the future we will support
generator expressions in INCLUDE_DIRECTORIES with $<> syntax, so the
fast-path in cmMakefile::ExpandVariablesInString will no longer be taken
and re-expansion will be very expensive.
Add policy CMP0019 to skip the re-expansion altogether in NEW behavior.
In OLD behavior perform the expansion but improve the fast-path
heuristic to match ${} but not $<>. If the policy is not set then warn
if expansion actually does anything. We expect this to be encountered
very rarely in practice.
Eliminate the platform difference in calling stat. We call stat normally
in other places in the CMake code base just fine. Works everywhere we
work. Will hopefully also fix the Borland Continuous dashboard failure
that is occurring with respect to correctly measuring the modification
time of a freshly generated file.
...revealed by the Nightly dashboard runs last night.

Fix warnings about shadowed "tmp" local variable and ordering of

Edition, so do not prohibit their use just because we detect the

Previously it was necessary for writers of Config files

add_custom_command can have empty DEPENDS arguments, which
was triggering invalid makefile generation for the NMake
Makefiles generator. We were mistakenly emitting the build
directory appended with "/" plus the empty string... which
was then translated to a string ending in \" in build.make...
which nmake choked on.
The solution is not to emit any dependency when the input
DEPENDS is the empty string. Return early from GetRealDependency
in this empty input case.
This is for consistency throughout cmake. The cmsys version exists
becaues uses of auto_ptr types as return types does not work with
some implementations in ancient compilers.

On some systems, ${QT_INCLUDE_DIR} is reported by gcc as a builtin
include search dir. Some projects use this information to extend
CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES.
In cmake 2.8.10 now the targets are queried for the include directories
they use. When they return the result, the include dirs contained in
CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES have been removed.
In cmake 2.8.9 and below the INCLUDE_DIRECTORIES directory property
was queried, where this had not been stripped.
So, in those projects which modify the implicit include dirs variable,
on systems where ${QT_INCLUDE_DIR} is reported by gcc, this directory,
e.g. /usr/lib/include/qt/, was not given anymore to moc. This made moc
not find required headers, so the build broke.
Simply giving the full CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES to moc
is no solution either, since moc can't handle some of the headers it
finds then (https://bugreports.qt-project.org/browse/QTBUG-28045).
So now cmake checks CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES, and if this
contains ${QT_INCLUDE_DIR}, and the target reports that it uses
${QT_QTCORE_INCLUDE_DIR} but not ${QT_INCLUDE_DIR}, ${QT_INCLUDE_DIR}
is added to the include dirs given to moc.

Pass the name of the requested generator to the generator factory,
which is now responsible to check if it can create a matching
generator for the name. This allows us to add more logic to the
factory in a next step, so that not every possible generator needs
to get registered explicit in cmake::AddDefaultGenerators().
Since ExtraGenerators does not contain items, which are in Generators
too, there is not change in behaviour. The benefit of this change is,
that the lookup in the Generators map is now only done once.
Since commit ca39c5cd (Optionally allow IMPORTED targets to be globally
visible, 2012-01-25) cmGlobalGenerator has a second member that tracks
targets with global scope. We must initialize the new 'ImportedTargets'
member wherever the old 'TotalTargets' member is initialized. Without
this initialization the ImportedTargets member is left with dangling
pointers during a same-process re-configuration.
This patch sets the FOLDER target property for the automoc target
to the same value as of the actual target. This organizes the targets
in IDEs with folders better.

Some dependency-generators (such as cmDependsFortran) generate multiple
entries per depender, so erasing the dependency vector for each depender
found loses earlier dependencies.
Signed-off-by: Michael Wild <themiwi@users.sourceforge.net>
This patch is heavily inspired by Michael Wild.
The interfaces cmDepends::Write and cmDepends::WriteDependencies where
extended to allow multiple dependees (sources) per depender (object).
cmDepends::Write first collect all dependencies into a std::set before
passing it to cmDepends::WriteDependencies.
cmDependsC::WriteDependencies also first collects all explicit and
implicit dependencies into a std::set and only then writes
depend.{internal,make}. The implementation of cmDependsFortran simply
loops over all sources and proceeds as before, whereas the cmDependsJava
implementation is as trivial as before.
This is for preventing exponential growth of depend.{internal,make} in
the next commit which fixes dependency-vector erasure in
cmDepends::CheckDependencies.

Commit 08cb4fa4 (Process generator expressions in the
INCLUDE_DIRECTORIES property, 2012-09-18) contained an incorrect
assumption that CMAKE_BUILD_TYPE was set on the makefile for each
generated configuration in multi-config generators. Fix that by making
the GetIncludeDirectories API depend on the config.
This fixes a regression introduced in commit 290e92ad (Move
GetIncludeDirectories to cmGeneratorTarget, 2012-09-16) which loops over
cmGeneratorTargets before they get created, so the container is empty.
Content which is incomplete as a generator expression could cause
segfaults by advancing an iterator beyond end() and dereferencing
it. Such incomplete generator expressions should be treated as
plain text instead.
The rationale is similar to that in commit b3d8f5da (GenEx: Parse comma
after colon tokens specially, 2012-10-04), in that colon tokens should
not be parsed as identifier-argument delimiters after the first colon.
Now automoc always uses GetRealPath() so symbolic links are always
resolved and it doesn't end up with twice the same file, once with the real
path and once with the symlinked path in some setups where the source dir
can be accessed directly and via a symlink

If the CMAKE_SUBLIMECLANG_DISABLED variable is on then SublimeClang
is disabled in the generated project file. This is useful in large
projects where SublimeClang might run slowly or perform poorly.
This adds -I include path flags and -D define flags for sublimeclang.
The current problem with this is that these flags cannot be set per
target (build_system in sublime text), it can only be set project
wide. Currently all of the include paths and compiler definitions from
ALL of the targets are used (with duplicates removed). This could be
problematic in some cases (conflicting compiler definitions among targets).
The generator adds all list and source files for each defined
project. The generated project files also include build_system
entries that run the platform-specific make on the generated
Makefiles. A build_system entry is created for each target
that was defined in the CMakeLists.txt files.
At the moment this has only been tested with C/C++ projects.

Additionally, this allows reporting the correct error for other
expressions. For example $<TARGET_PROPERTY:,> should be invalid
because it has an empty target and empty property. It shouldn't
attempt to read the property ',' on the 'implicit this' target.
