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.
4ad0233 Remove period at the end of the check message.
50b1ea5 Fix minor typos.
19c3206 Remove unused parameter marker and the unused parameter.
9d462b2 Document that generator expressions can be used in target properties.
daf88c3 Fix punctuation in some variables documentation.
3172cde Fix the layout of the generator expression documentation.
This way we don't need to check the definitions from the Makefile when
generating later, and can more easily add generator expressions.
Duplication is not a problem as the definitions are de-duplicated before
generating.
At the top of a build tree we configure inside the CMakeFiles directory
files such as "CMakeSystem.cmake" and "CMake<lang>Compiler.cmake" to
save information detected about the system and compilers in use. The
method of detection and the exact results store varies across CMake
versions as things improve. This leads to problems when loading files
configured by a different version of CMake. Previously we ignored such
existing files only if the major.minor part of the CMake version
component changed, and depended on the CMakeCache.txt to tell us the
last version of CMake that wrote the files. This led to problems if the
user deletes the CMakeCache.txt or we add required information to the
files in a patch-level release of CMake (still a "feature point" release
by modern CMake versioning convention).
Ensure that we always have version-consistent platform information files
by storing them in a subdirectory named with the CMake version. Every
version of CMake will do its own system and compiler identification
checks even when a build tree has already been configured by another
version of CMake. Stored results will not clobber those from other
versions of CMake which may be run again on the same tree in the future.
Loaded results will match what the system and language modules expect.
Rename the undocumented variable CMAKE_PLATFORM_ROOT_BIN to
CMAKE_PLATFORM_INFO_DIR to clarify its purpose. The new variable points
at the version-specific directory while the old variable did not.
When a language is not enabled at the top level of a project but is
enabled in multiple disjoint subdirectories we should re-use the
CMake<lang>Compiler.cmake file from the first directory. Load the file
whenever it exists and is not left from a different version of CMake.
bd34963 Refactor generation of shared library flags
55d7aa4 Add platform variable for flags specific to shared libraries
31d7a0f Add platform variables for position independent code flags
CMAKE_SHARED_LIBRARY_<lang>_FLAGS has flags on various platforms for a
variety of purposes that are correlated with shared libraries but not
exclusive to them. Refactor generation of these flags to use new
purpose-specific platform variables
CMAKE_<lang>_COMPILE_OPTIONS_DLL
CMAKE_<lang>_COMPILE_OPTIONS_PIC
CMAKE_<lang>_COMPILE_OPTIONS_PIE
Activate the DLL flags specifically for shared libraries. Add a new
POSITION_INDEPENDENT_CODE target property to activate PIC/PIE flags, and
default to true for shared libraries to preserve default behavior.
Initialize the new property from CMAKE_POSITION_INDEPENDENT_CODE to
allow easy global configuration in projects.
Although the default behavior is unchanged by this refactoring, the new
approach ignores CMAKE_SHARED_LIBRARY_<lang>_FLAGS completely. We must
leave it set in case projects reference the value. Furthermore, if a
project modifies CMAKE_SHARED_LIBRARY_<lang>_FLAGS it expects the new
value to be used. Add policy CMP0018 to handle compatibility with
projects that modify this platform variable.
Add a PositionIndependentCode test on platforms where we can get
meaningful results.
Add cmGlobalGenerator::GenerateRuleFile to compute a generator-specific
rule file location. This will allow specific generators to override the
location of .rule files without changing the behavior of other
generators.
Rename cmGlobalGenerator::GetCMakeCFG{InitDirectory => IntDir} to
have a shorter name without a typo. Add a 'const' qualifier since
the method is only for lookup and never needs to modify anything.
Add a virtual cmGlobalGenerator::ComputeTargetObjects method invoked
during cmGeneratorTarget construction. Implement it in the Makefile
generator to pre-compute all object file names for each target. Use
the results during generation instead of re-computing it later.
Construct the instances after the final set of targets is known but
before computing inter-target dependencies. This order will allow
initialization of cmGeneratorTarget instances to adjust and finalize
declared inter-target dependencies.
Eliminate callers of cmMakefile::GetIncludeDirectories.
All callers of GetIncludeDirectories should go through the local generator
object.
Only the local generator calls cmTarget::GetIncludeDirectories directly.
Consider the case motivating commit e01cce28 (Allow add_dependencies()
on imported targets, 2010-11-19). An imported target references a file
generated at build time by a custom target on which it depends. Had the
file been built directly using add_library or add_executable its target
name would have been visible globally. Therefore the imported target
representing the file should be globally visible also.
Teach the IMPORTED signature of add_(executable|library) to accept a new
"GLOBAL" option to make the imported target visible globally.

During a try_compile cmGlobalGenerator::EnableLanguage uses results from
the outer project. Reject attempts to enable languages in the test
project that are not "ready" in the outer project. Mark a language as
"ready" when all its information has been loaded and we are ready to
generate build rules.
This also avoids infinite recursion introduced by commit 295b5b60 (Honor
CMAKE_USER_MAKE_RULES_OVERRIDE in try_compile, 2010-06-29) for projects
that set CMAKE_USER_MAKE_RULES_OVERRIDE to a file that uses try_compile.
The file is loaded along with the information for a given langauge so
the language is not yet "ready".

Remove a boolean parameter of cmGlobalGenerator::CreateGlobalTarget that

because no global targets exist before it runs anymore.
Visual Studio Express editions do not support solution folders,
so default behavior should be as if USE_FOLDERS global property
is OFF.
Also, allow folder names to be the same as target names: internally,
use a prefix to distinguish folder GUIDs from target GUIDs. Add
a target and folder with the same name in the ExternalProject
test to exercise this code.
For CMake itself, provide a new option CMAKE_USE_FOLDERS that
defaults to ON so that Visual Studio users get a nicely organized
CMake project. Express edition users will have to turn off the
CMAKE_USE_FOLDERS option in order to build CMake in the VS Express
IDE.
Since commit bc43b0f2 (Do not link library dependencies in VS solutions,
2009-10-20) CMake disables for VS >= 8 linking of a target to libraries
that happen to be listed as solution-level dependencies. Therefore we
can list the direct dependencies of each target in the solution file and
let VS handle transitive dependencies automatically.
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.
