Brad King e1c7747253 Format include directive blocks and ordering with clang-format
Sort include directives within each block (separated by a blank line) in
lexicographic order (except to prioritize `sys/types.h` first).  First
run `clang-format` with the config file:

    ---
    SortIncludes: false
    ...

Commit the result temporarily.  Then run `clang-format` again with:

    ---
    SortIncludes: true
    IncludeCategories:
      - Regex:    'sys/types.h'
        Priority: -1
    ...

Commit the result temporarily.  Start a new branch and cherry-pick the
second commit.  Manually resolve conflicts to preserve indentation of
re-ordered includes.  This cleans up the include ordering without
changing any other style.

Use the following command to run `clang-format`:

    $ git ls-files -z -- \
        '*.c' '*.cc' '*.cpp' '*.cxx' '*.h' '*.hh' '*.hpp' '*.hxx' |
      egrep -z -v '(Lexer|Parser|ParserHelper)\.' |
      egrep -z -v '^Source/cm_sha2' |
      egrep -z -v '^Source/(kwsys|CursesDialog/form)/' |
      egrep -z -v '^Utilities/(KW|cm).*/' |
      egrep -z -v '^Tests/Module/GenerateExportHeader' |
      egrep -z -v '^Tests/RunCMake/CommandLine/cmake_depends/test_UTF-16LE.h' |
      xargs -0 clang-format -i

This selects source files that do not come from a third-party.

Daniele E. Domenichelli 4db31095e5 Fix link line order when shared libraries are de-duplicated
Since commit v3.1.0-rc1~227^2~1 (De-duplicate shared library targets in
generated link lines, 2014-07-30) we de-duplicate shared library targets
on the link line.  However, some toolchains will fail linking if an
executable is linking to a shared library that is not used directly and
a static library that depends on the shared one.  The linker may not
keep the reference to the shared library the first time and then the
symbols needed by the static library may not be found.

Fix this by reversing the direction of the for loop that removes the
duplicate shared libraries, in order to ensure that the last occurrence
of the library is left instead of the first one.

Extend Tests/Dependency with a case covering this behavior.  Create an
executable that links to a shared library and a static library but only
needs the shared library as a dependency of the static library.

Brad King 9f7e27fc3a De-duplicate shared library targets in generated link lines
The linker will bring in shared libraries as a whole and use them even
for symbols that are needed by entries later in the link line.
Therefore we do not need to repeat them.  De-duplicate link entries that
we know are shared libraries because we have a cmTarget associated with
them.

Brad King d912220eaa cmTarget: Lookup targets in LinkInterface and LinkImplementation
Instead of storing just the string names in these structures, lookup any
target associated with each item and store its cmTarget pointer.  Use
the cmLinkItem class to hold the name and pointer together.  Update
client sites to use the pre-stored lookup result instead of looking up
the target name again.

Create a cmTarget::LookupLinkItems helper method to handle the lookup.
Since lookups are now moving from cmComputeLinkDepends::AddLinkEntries
to cmTarget::LookupLinkItems, move use of CheckCMP0004 to the latter.
This drops use of CheckCMP0004 from entries added for _LIB_DEPENDS
variables by cmComputeLinkDepends::AddVarLinkEntries, but I do not
think that use was intentional originally anyway.

Brad King 0dc9e88d76 cmTarget: Remove 'head' argument from GetLinkImplementation
Many of the 'head' arguments added by commit v2.8.11~289^2~1 (Make
linking APIs aware of 'head' target, 2013-01-04) turned out not to be
needed.  The "link implementation" of a target never needs to be
computed with anything but itself as the 'head' target (except for
CMP0022 OLD behavior because then it is the link interface).

Remove the unused 'head' target paths.  Add "internal" versions of
cmTarget::GetDirectLinkLibraries and GetLinkImplementationLibraries
to support the CMP0022 OLD behavior without otherwise exposing the
'head' target option of these methods.

Ben Boeckel 270eb96df0 strings: Remove cmStdString references
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.

The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.

Stephen Kelly fe732264e9 Add the INTERFACE_LIBRARY target type.
This target type only contains INTERFACE_* properties, so it can be
used as a structural node. The target-specific commands enforce
that they may only be used with the INTERFACE keyword when used
with INTERFACE_LIBRARY targets. The old-style target properties
matching LINK_INTERFACE_LIBRARIES_<CONFIG> are always ignored for
this target type.

The name of the INTERFACE_LIBRARY must match a validity generator
expression. The validity is similar to that of an ALIAS target,
but with the additional restriction that it may not contain
double colons. Double colons will carry the meaning of IMPORTED
or ALIAS targets in CMake 2.8.13.

An ALIAS target may be created for an INTERFACE library.

At this point it can not be exported and does not appear in the
buildsystem and project files are not created for them. That may
be added as a feature in a later commit.

The generators need some changes to handle the INTERFACE_LIBRARY
targets returned by cmComputeLinkInterface::GetItems. The Ninja
generator does not use that API, so it doesn't require changes
related to that.

Stephen Kelly 40cf3fb95b Make linking APIs aware of 'head' target
The 'head' is the dependent target to be linked with the current target.
It will be used to evaluate generator expressions with proper handling
of mapped configurations and is used as the source target of properties.

This requires that memoization is done with a key of a pair of target
and config, instead of just config, because now the result also depends
on the target.  Removing the memoization entirely is not an option
because it slows cmake down considerably.

Brad King b87d7a60a0 Add OBJECT_LIBRARY target type
This library type can compile sources to object files but does not link
or archive them.  It will be useful to reference from executable and
normal library targets for direct inclusion of object files in them.

Diagnose and reject the following as errors:

* An OBJECT library may not be referenced in target_link_libraries.

* An OBJECT library may contain only compiling sources and supporting
  headers and custom commands.  Other source types that are not normally
  ignored are not allowed.

* An OBJECT library may not have PRE_BUILD, PRE_LINK, or POST_BUILD
  commands.

* An OBJECT library may not be installed, exported, or imported.

Some of these cases may be supported in the future but are not for now.

Teach the VS generator that OBJECT_LIBRARY targets are "linkable" just
like STATIC_LIBRARY targets for the LinkLibraryDependencies behavior.

Brad King 8e756d2b9b Tolerate cycles in shared library link interfaces (#12647)
Since commit 183b9509 (Follow all dependencies of shared library private
dependencies, 2011-12-14) we honor LINK_INTERFACE_LIBRARIES when
following dependent shared libraries.  The link interface properties may
form a cycle if set incorrectly by a project.  Furthermore, the property
LINK_DEPENDENT_LIBRARIES may form a cycle if set incorrectly by hand
(though CMake should never generate one).  In either case, do not follow
the cycle forever when following the dependent shared library closure.
We only need to add dependency edges to the constraint graph once.

Add "LinkInterfaceLoop" test to cover this case.

Brad King 183b95098e Follow all dependencies of shared library private dependencies
In cmComputeLinkDepends we compute the transitive closure of private
shared library dependencies.  When a shared library is added to this
closure we must follow all of its dependencies whether they are private
or public.  Previously we only followed the private dependencies.  Fix
the implementation to follow the public dependencies too.  Also extend
the ExportImport test to cover this case.
