This reverts commit de4da665d3.

This feature is not yet ready for release. It needs to be
merged with the CMAKE_OSX_SYSROOT feature.

Brad King 77ac9b8b9c VS12: Add Visual Studio 12 generator (#14251)
Copy cmGlobalVisualStudio11Generator to cmGlobalVisualStudio12Generator
and update version numbers accordingly.  Add the VS12 enumeration value.
Add module CMakeVS12FindMake to find MSBuild.  Look for MSBuild in its
now-dedicated Windows Registry entry.  Teach the platform module
Windows-MSVC to set MSVC12 and document the variable.  Teach module
InstallRequiredSystemLibraries to look for the VS 12 runtime libraries.

Teach tests CheckCompilerRelatedVariables, Preprocess, VSExternalInclude,
and RunCMake.GeneratorToolset to treat VS 12 as they do VS 10 and 11.

Stephen Kelly de4da665d3 Use --sysroot when cross compiling.
As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is
introduced, which is never a list.

The contents of this variable is passed to supporting compilers
as --sysroot. It is also accounted for when processing implicit
link directories reported by the compiler, and when generating
RPATH information.

Brad King 42ba1b08f3 VS: Separate compiler and linker PDB files (#11899, #14062)
The MS tools create two types of PDB files as explained here:

 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.71%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.80%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.90%29.aspx
 http://msdn.microsoft.com/en-us/library/yd4f8bd1%28v=vs.100%29.aspx

One is created by the compiler (/Fd) and the other by the linker (/pdb).
The two options should not specify the same file.  Split them up.

In the VS IDE generators, simply drop ProgramDataBaseFileName to
take the VS default "/Fd$(IntDir)vc$(PlatformToolsetVersion).pdb".

In the Makefile generators, set "/Fd" on the compile line to be
the directory containing object files (with a trailing slash the
compiler will add the "vc$(PlatformToolsetVersion).pdb" filename
automatically).  Drop the /Fd option from the exe link command
line and add "/pdb" instead (already done for dll linking).
Update these rules for both MSVC and Intel tools.

Drop support for PDB_OUTPUT_DIRECTORY and PDB_NAME in STATIC
libraries because the generated .pdb files are only from /Fd
and not real linker-generated .pdb files.  Update documentation to
clarify that the PDB_* properties are only for linker .pdb files.

This regresses the PDBDirectoryAndName test for STATIC libraries.
Since it is not clear at this time what should be done for STATIC
library .pdb files, comment out the relevant portion of the test
and leave a TODO comment.

Brad King baa33acbda AIX-GNU: Put implicit link directories in runtime libpath (#13909)
The GNU compiler front-ends on AIX invoke the linker with flags of the
form "-L/path/to/gnu/runtime/lib" to tell ld where to find the language
runtime libraries.  They depend on the default libpath behavior
documented in "man ld" to add the -L paths also to the runtime libpath
so the dynamic loader can find the language runtime libraries.  This
differs from platforms whose linkers have distinct -rpath flags that
non-system compilers can use to tell the dynamic loader where to find
their language runtime libraries.

Since commit 96fd5909 (Implement linking with paths to library files,
2008-01-22) CMake always passes "-Wl,-blibpath:" followed by any
project-defined RPATH plus "/usr/lib:/lib" in order to explicitly set
the runtime libpath and avoid getting all the project -L paths in the
runtime libpath.  The explicit libpath prevents the GNU compiler runtime
library -L paths from being placed in the libpath and then the dynamic
loader fails to find the language runtime libraries.

CMake already detects the implicit link directories for each language
since commit 07ea19ad (Implicit link info for C, CXX, and Fortran,
2009-07-23).  Add the implicit link directories to the explicit runtime
libpath for GNU compilers on AIX to fix this use case.

Stephen Kelly 9ce1b9ef29 Add CMAKE_BUILD_INTERFACE_INCLUDES build-variable.
This makes

 set(CMAKE_BUILD_INTERFACE_INCLUDES ON)

add the equivalent of

 set_property(TARGET tgt APPEND PROPERTY
   INTERFACE_INCLUDE_DIRECTORIES
   $<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR};${CMAKE_CURRENT_BINARY_DIR}>
 )

to every target.

If the headers are in CMAKE_CURRENT_SOURCE_DIR, and the generated headers
are in CMAKE_CURRENT_BINARY_DIR, this is a convenient way to build a target
bar, which depends on foo, just by using target_link_libraries() and adding
the INTERFACE_INCLUDE_DIRECTORIES to the INCLUDE_DIRECTORIES of the target
being linked. There will be more-convenient porcelain API to consume the
property in the future.

Brad King cc676c3a08 OS X: Detect implicit linker framework search paths
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.

Stephen Kelly bd34963002 Refactor generation of shared library 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.
