Thanks to Pau Garcia i Quiles for the inspiration for the patch.
I've tweaked it a bit compared to what's in the bug tracker: this
commit does not allow empty global variable names.
I also added usage of the new feature to an existing test. Although
it has no effect on the resulting Visual Studio projects, you can
verify that the VSResource test produces a non-empty globals section
in the generated .vcproj(x) files.
set_property() has APPEND, which creates a list. E.g. when
appending to COMPILE_FLAGS a string is needed, not a list.
With the APPEND_STRING option the value is append as string,
not as list.

added by commit c6a8e4c7 (The link interface of MODULE libraries is
empty, 2011-03-09).
MODULE libraries cannot be linked into other libraries and executables
(just like executables without ENABLE_EXPORTS). Set the MODULE target
link interface to be empty. This allows such targets to be installed in
an EXPORT set without including all their private implementation
dependencies.
Commit afd7d4ca (Add target property LINK_SEARCH_END_STATIC, 2008-01-31)
defined a property to ensure that static runtime libraries get selected.
Add a property to specify that all libraries whose type is unknown, such
as "-lm", should be assumed static. Furthermore it assumes that an
option such as "-static" is also used so that no initial -Bstatic is
needed.
Although the LOCATION property is for compatibility with CMake 2.4, the
LOCATION_<CONFIG> property is modern. However, if a project reads it
and sets location-altering properties later the behavior is undefined.
See parent commit for details.
Reading the LOCATION target property currently locks down the result and
ignores any later changes to properties that affect it. This may or may
not be expected and may or may not be the behavior in earlier versions
of CMake. The property is documented as provided only for compatibility
with CMake 2.4 and alternative interfaces are now available for all
originally envisioned use cases. We want to discourage its use without
outright deprecating it. Add documentation to explicitly state that
reading the property before other properties are set is undefined.

Evaluate in the COMMAND arguments of custom commands the generator
expression syntax introduced in commit d2e1f2b4 (Introduce "generator
expressions" to add_test, 2009-08-11). These expressions have a syntax
like $<TARGET_FILE:mytarget> and are evaluated during build system
generation. This syntax allows per-configuration target output files to
be referenced in custom command lines.
The soname generation code was compile-time selected instead of runtime
selected. The result is that a Mac-compiled cmake used to cross-compile
Mac -> Unix generates an soname of the form libfoo.x.y.so instead of
libfoo.so.x.y as expected. Instead do a runtime check based on the
target platform.

Avoid tracing dependencies of GLOBAL_TARGET targets. The build system
generators are not designed to handle any dependencies that may be
discovered. Global targets are only generated by CMake and never have
commands that reference targets built in the project anyway.
The exception is when building CMake itself there is a special case to
use the just-built "cmake" binary in the "install" target so that CMake
can replace itself on Windows. Even in this special case we do not want
to let the "install" target depend on the "cmake" target. Doing so
breaks cases like "make -j4 install".
Imported targets do not themselves build, but we can follow dependencies
through them to find real targets. This allows imported targets to
depend on custom targets that provide the underlying files at build
time.
Factor out reading of CMAKE_CONFIGURATION_TYPES and CMAKE_BUILD_TYPE
into cmMakefile::GetConfigurations. Read the former only in
multi-config generators.
This work was started from a patch by Thomas Schiffer.
Thanks, Thomas!
See the newly added documentation of the FOLDER target
property for details.
Also added global properties, USE_FOLDERS and
PREDEFINED_TARGETS_FOLDER. See new docs here, too.
By default, the FOLDER target property is used to organize
targets into folders in IDEs that have support for such
organization.
This commit adds "solution folder" support to the Visual
Studio generators. Currently works with versions 7 through
10.
Also, use the new FOLDER property in the ExternalProject
test and in the CMake project itself.
Cygwin versions .dll files by putting the version number in the file
name. Our fix to issue #3571 taught CMake to do this, but it used the
VERSION target property. It is better to use the SOVERSION property
since that is the interface (rather than implementation) version.
Change based on patch from issue #10122.
We create per-configuration target properties to specify ARCHIVE,
LIBRARY, and RUNTIME output directories. The properties override the
generic properties for the <CONFIG> configuration:
ARCHIVE_OUTPUT_DIRECTORY -> ARCHIVE_OUTPUT_DIRECTORY_<CONFIG>
LIBRARY_OUTPUT_DIRECTORY -> LIBRARY_OUTPUT_DIRECTORY_<CONFIG>
RUNTIME_OUTPUT_DIRECTORY -> RUNTIME_OUTPUT_DIRECTORY_<CONFIG>
For multi-configuration generators, the per-configuration subdirectory
normally appended to the generic output directory is not added to the
configuration-specific property values. This allows projects to set the
exact location at which binaries will be placed for each configuration.
See issue #9163.
The CMAKE_OSX_ARCHITECTURES variable works only as a global setting.
This commit defines target properties
OSX_ARCHITECTURES
OSX_ARCHITECTURES_<CONFIG>
to specify OS X architectures on a per-target and per-configuration
basis. See issue #8725.
The commit "Target copy ctor should copy internal state" created a new
cmTargetInternals constructor but failed to initialize a POD member that
the original constructor initializes. This commit fixes it.
Ideally we should never copy cmTarget instances, but it is a pain to
remove current uses of it. The pimplized portion of cmTarget has mostly
members that cache results, but some are part of the object state.
These should be copied in the copy ctor instead of re-initialized.
In cmTarget we compute the link implementation, link interface, and link
closure structures on-demand and cache the results. This commit teaches
cmTarget to invalidate results after a LINK_INTERFACE_* property changes
or a new link library is added. We also clear the results at the end of
the Configure step to ensure the Generate step uses up-to-date results.
In cmTarget::SetProperty and cmTarget::AppendProperty we check whether
changing the property invalidates cached information. The check was
duplicated in the two methods, so this commit moves the check into a
helper method called from both.
This method is called during ConfigureFinalPass on every target. It
gives each target a chance to do some final processing after it is known
that no more commands will affect it. Currently we just call the old
AnalyzeLibDependencies that used to be called directly.
This commit creates target and directory properties to enable the Intel
interprocedural optimization support on Linux. Enabling it adds the
compiler option '-ipo' and uses 'xiar' to create archives.
See issue #9615.
This creates cmTarget::GetFeature and cmMakefile::GetFeature methods to
query "build feature" properties. These methods handle local-to-global
scope and per-configuration property lookup. Specific build features
will be defined later.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
In each target we trace dependencies among custom commands to pull in
all source files and build rules necessary to complete the target. This
commit teaches cmTarget to save the inter-source dependencies found
during its analysis. Later this can be used by generators that need to
topologically order custom command rules.
In cmTarget we trace the dependencies of source files in the target to
bring in all custom commands needed to generate them. We clean up the
implementation to use simpler logic and better method names. The new
approach is based on the observation that a source file is actually an
input (dependency) of the rule that it runs (compiler or custom) even in
the case that it is generated (another .rule file has the rule to
generate it).
This teaches cmTarget to use a set of cmSourceFile pointers to guarantee
unique insertion of source files in a target. The order of insertion is
still preserved in the SourceFiles vector.
We create target property "LINK_INTERFACE_MULTIPLICITY" and a per-config
version "LINK_INTERFACE_MULTIPLICITY_<CONFIG>". It sets the number of
times a linker should scan through a mutually dependent group of static
libraries. The largest value of this property on any target in the
group is used. This will help projects link even for extreme cases of
cyclic inter-target dependencies.
